Dr. Neha Bhatt: 我是WebMD首席医生编辑Neha Bhatt医生,今天我们将讨论听力损失。如果您曾经觉得周围的人都在含糊不清地说话,或者在嘈杂的环境中难以跟上谈话,或者注意到您所爱的人在有大量背景噪音的情况下难以跟踪谈话,那么您并不孤单。听力损失可能在任何年龄段悄然而至,通常没有明显的预警信号。对于我们中的一些人来说,听力损失可能是由年龄相关的退化引起的。对于其他人来说,它可能是由持续的噪音暴露、某些药物、耳垢堵塞、慢性耳感染甚至头部创伤引起的。在本期节目中,我们将逐步探讨听力损失,探索可能预示听力问题的明显线索,我们可用的筛查和全面测试,以及听力损失如何随着时间的推移令人惊讶地影响心理和认知健康。我们还将分解保护耳朵的日常步骤,从了解安全的噪音水平到认识到何时可以使用非处方设备以及何时需要更深入的评估。我们将回答您一些最紧迫的问题,例如,随着年龄的增长,轻微的听力障碍是否正常?或者它是否隐藏着潜在的疾病?如何才能在医疗预约期间为自己或您所爱的人争取权益,以确保您获得正确的测试和解决方案? Dr. Douglas Beck: 感谢邀请。我很荣幸来到这里。我非常兴奋地开始我们的谈话。但在我们开始之前,我想问一下您自己关于与患者合作以及与听力损失相关的个人健康发现,您的顿悟时刻。我的顿悟时刻实际上始于1983年或1984年在洛杉矶的House Ear Institute的奖学金。在那之前几年,FDA批准了用于成人的人工耳蜗植入物。这让我了解了许多即将出现的关于神经生理学和技术的知识。我当时身处正确的时间和地点。我很感激能在那里。我很高兴谈谈现在可供患者使用的所有这些选择。感谢您以此开启我们的讨论。在我们开始之前,我想先退一步,从基础知识开始。人们常常认为听力损失是与年龄相关的。您能跟我们谈谈一般的听力损失吗?我们应该如何看待它?这真的是我们随着年龄增长需要开始考虑的事情吗?或者在我们的一生中,我们应该考虑哪些事情?听力只是感知或检测声音。大概90%患有严重听力损失的人都能够听到声音。他们做不到的是理解。他们做不到的是理解声音。他们做不到的是理解声音。因此,这让我们想到了这样一个问题:听和听觉。听是感知或检测声音。听觉是理解声音。在美国,我们大约有3.4亿人口。大约五分之一的人患有听力损失。在美国,还有2600万到2800万人根本没有听力损失,但他们在理解方面有困难,尤其是在嘈杂的环境中。当我们谈论听力和听觉时,这两者之间有着密切的联系,你不能把它们分开。听觉是第一步。你必须感知声音,但更大的任务是让你的大脑理解你听到的内容。在美国,大约97%到98%的婴儿出生时都会进行立即的听力测试。这是通过筛查进行的。有两种类型的筛查。一种称为耳声发射,我们让一些声音从耳膜反弹,然后测量反射的声音。然后我们还可以进行听觉脑干反应测试。同样,我们只是在耳朵里发出轻微的咔哒声,然后测量大脑的反应。这告诉我们患者或儿童是否能够听到声音。这就是它告诉我们的全部信息。它并没有告诉我们很多细节。当你进入幼儿园或学前班时,你可能会进行听力测试。但这些只是筛查。听力筛查的问题在于,它们不会测试你理解声音的能力。它们只会告诉你是否能听到声音。因此,这不足以做出良好的决定。许多无法理解但能够听到声音的孩子可能患有注意力缺陷障碍、注意力缺陷多动障碍、阅读障碍。他们可能患有各种各样的特定语言障碍。言语和听力问题在幼儿中经常同时出现。因此,孩子通过听力测试并不意味着他或她能够理解老师。我们对青少年进行的测试非常有趣,它们是如何发展的。它们基本上是在寻找耳部疾病。尤其是在儿童中,我们正在寻找的是确保两只耳朵都能工作,并且我们正在寻找的是,从本质上讲,你知道,这个孩子是否患有中耳炎,中耳感染?他们的耳膜是否穿孔?他们的耳朵里有很多粘液,这可能是耳垢,也称为耳垢,以及其他与耳朵相关的身体疾病。但有趣的是,这在成年人中,只有大约5%到8%的听力损失是由医疗问题引起的。大多数听力损失都可追溯到你之前谈到的问题。年龄相关的听力损失、噪音引起的听力损失、耳毒性药物、头部创伤。这些都会导致听力和听觉困难。但是,当我们进行筛查时,我们只是在寻找听力损失的医疗原因。老实说,我认为我们必须改变这种做法。我认为对成年人或儿童进行筛查是不合适的。我认为每个人都应该进行全面的听力学评估。这实际上是大多数保险公司支付的费用。特别是,医疗保险实际上称之为全面的听力学评估,因为我们知道,筛查不适合有听力或听觉障碍迹象或症状的人群。只要他们没有听力问题和听觉问题,筛查对普通人群来说是可以的。听力筛查就像视力中的斯内伦视力表一样。你知道那些你站在20英尺远的地方阅读你能看到的最小一行字的图表吗?这很有用。它告诉你你能看到还是不能看到,但它并没有告诉你关于你实际视力的足够信息,以便对你视力健康做出任何好的决定。然后,请你再详细地告诉我一些关于你所说的这种全面评估的内容。它包括什么内容?它会告诉你什么?是的,当你听到声音时按下按钮。这是一个筛查。这并没有什么用。全面的听力学评估是美国听力学学会推荐的。这是美国言语语言听力协会推荐的。这是国际听力协会推荐的。他们在这些全面的听力学评估中所做的是,我们进行当你听到哔哔声时按下按钮的操作,这是第一级。但我们也进行言语识别测试。我们一次一个地将数字化单词播放到你的耳朵里。我们记录你在安静环境下的听力情况。但现实情况是,大多数人不会在安静的环境中倾听。你在嘈杂的环境中倾听,这就是问题所在。因此,所有三种最佳实践模式,AAA、ASHA和IHS都说你应该进行言语和噪音测试。我们有经过校准的言语和噪音测试,可以准确地告诉我们一个人在困难的、具有挑战性的倾听环境中的表现如何,例如家庭聚会、鸡尾酒会、餐馆。对我来说,作为一名听力学家,这些比当你听到哔哔声时按下按钮更重要。再次强调,听力并不是最终目的。听觉意味着你已经听到它并且能够理解它。因此,如果我必须在听力和听觉之间做出选择,我想要一个听觉评估,因为它在临床上告诉我患者的功能如何?他们在现实世界中表现如何?对我来说,这比哔哔声告诉我更多信息。这很好,非常有帮助。然后我有两个后续问题。第一个是,谁会自己进行这种评估?这是注意到,“哦,我有一些困难”的人吗?或者这是你所说的应该在一生中定期进行的事情吗?第二个问题是,这些测试应该多久进行一次?不幸的是,大多数医疗保健专业人员在意识到患者有听力或听觉问题时,会说,“哦,你应该去做个筛查。”这导致患者去进行筛查。然后我们仍然没有足够的信息来充分讨论该个人的情况。我相信,如果让我来制定规则,我没有权力这样做,但如果让我来制定规则,我会说每个孩子出生时都应该进行听力筛查,这现在已经非常普遍了。这被称为普遍新生儿听力筛查。他们应该在进入学前班、幼儿园或小学之前进行全面的听力学评估。然后我认为,如果没有听力或听觉困难的迹象或症状,他们可能五年不需要再做一次。但我希望每五年做一次。我认为对于成年人来说,大多数成年人都记不起他们是否曾经做过全面的听力学评估。他们所做的是说,诸如此类的事情。每个人都在含糊不清地说。你有没有注意到,突然之间每个人都在含糊不清地说?人们不再清晰地说话了。当我还是个孩子的时候,每个人都必须学习清晰地发音,然后他们会告诉你关于选择性听觉和其他所有事情。从他们的角度来看,这绝对是准确的。他们会说人们含糊不清地说。从他们的角度来看,绝对是准确的。但你知道真正发生的事情是什么吗?实际上,他们并没有听到高频声音,因为噪音引起的听力损失或年龄相关的听力损失或耳毒性问题。也许他们长期服用利尿剂。也许他们服用过量非处方药,可能是阿司匹林。可能是某些利尿剂、抗生素。因此,当我们有这些暴露时,我们往往会首先失去高频声音。在过去一两年中,哈佛大学出现了一些非常有趣的新信息。众所周知,自从二战以来,自从邦贝克希以来,人类的听力范围大约是从20赫兹到20000赫兹。因此,当你进行听力测试时,有一些事情需要注意,该听力图只从250赫兹到8000赫兹。这意味着你没有对钢琴上中音C以下的任何音符进行测试。钢琴的整个左侧在听力测试中没有显示出来。此外,当某人出生时听力范围为18000赫兹或20000赫兹时,我们直到听力下降到8000赫兹时才会在听力图上注意到任何听力损失。当它影响到8000赫兹时,理论上你已经损失了10000赫兹或12000赫兹,或者你的听力损失远远超过了测试的范围。这会导致诸如耳鸣等问题。这会导致在困难的、具有挑战性的情况下无法清晰地听到声音。人们认为两只耳朵是一样的,它们应该是对称的。但事实是这样的。如果你和我现在正在进行讨论,而你离我的右耳一米远,我的右耳在这些频率下以5000、6000和7000赫兹听到你的声音。比我的左耳响约20分贝。因此,我们听到所有这些声音非常重要。这就是人们如何在嘈杂的环境中理解发生的事情的方式。这就是人们能够根据两只耳朵之间响度差异和时间差异来定位声音的方式。这就是人们能够根据两只耳朵之间响度差异和时间差异来估计距离的方式。大多数人从来都没有想过这些。但同样,这些都是我们想要进行言语和噪音测试的原因。这些是我们想要进行扩展高频测试的原因。这些是听力学家应该进行听力和沟通评估的原因。再次强调,所有这些都与美国听力学学会、美国言语语言听力协会以及国际听力协会的最佳实践建议完全一致。不幸的是,只有大约15%或20%的听力保健专业人员会做这项工作,因为这通常受到你的保险公司的限制。你知道,他们根本不会为此付费。临床医生总是处于同样的境地。我相信你作为一名医生也是如此,你知道你想做什么,但你也知道病人被困住了,因为他们的保险不支付费用。因此,我们往往会少做一些我们可能更愿意做的事情。因此,结果是,我们利用较少的信息做出决定。仅从我们到目前为止讨论的内容来看,您确实帮助我们确定了一些风险因素。因此,考虑到噪音引起的、年龄相关的、某些可能起作用的药物。您还让我们对我们可能失去听力的一些迹象、症状或危险信号有了一个非常有趣的了解。因此,认为每个人都在含糊不清地说,在有背景噪音的谈话中遇到这种困难。您还介绍了理想情况下应该做什么。因此,当您开始怀疑这些事情或开始描述这些迹象、症状或危险信号时,如果您作为初级保健提供者来到我的办公室,我会将您转介给听力学家进行进一步评估。您说即使在那里,人们也可能没有得到他们应该得到的全方位评估。那么,您能谈谈……更多我可能错过的、我还没有提到的其他危险信号,以及……那么,我们如何与听力学家进行这样的谈话,以确保我们能够进行全方位的测试呢?这里有很多内容需要展开。我认为我们必须做的主要事情是,我们必须对听力学家、牙医、儿科医生、耳鼻喉科医生说,你是否按照你国家协会的最佳实践进行操作?几乎每个人都想说是的。但是,你知道,这开启了这样的讨论,好吧,你知道,我们做我们认为需要做的事情。我们让迹象和症状指导我们的测试方案。这没关系。但对于听力和视力来说,这是我们两个主要的感觉。如果我们不彻底检查它们,我们就无法彻底了解正在发生的事情。所以这里有一个关于听力和听力损失的有趣的事情需要考虑。当某人患有听力损失时,他们绝对没有办法知道这一点。当你视力下降时,你可以看报纸,你会意识到你无法阅读它。你可以看看你的驾驶执照,你会意识到你无法阅读它。你可以看看你的手机,你无法阅读它。对于听力损失,你无法知道你没有听到什么。如果我们不进行全面的测试,其他人也不知道你没有听到什么。我认为这总是很困难,因为……医疗保健的很多方面都很昂贵。从视力检查到牙科检查,到整形外科手术,到脑外科手术,所有的一切都很昂贵。因此,问题是,我们能否找到一种方法,确保那些有困难的人能够得到诊断,然后与他们的听力保健提供者或医疗保健提供者一起,他们可以规划出最适合他们的道路。但这总是从最佳实践开始的,因为当我们从任何医疗或保健学科获得最佳实践时,我们知道这些都是非常有学问的人,他们查阅了文献,查阅了几十年,如果不是几个世纪的数据,并说,这就是我们应该做的。现在,少做一些有时更具成本效益。我明白了。但我认为我们必须确保我们首先要有一个诊断,然后是治疗。这里没有什么新鲜事。先诊断,后治疗,这始终符合患者的最佳利益。然后,让我们更深入地讨论一下诊断部分,听力损失有很多不同的原因。有些人可能会认为是良性的。所以这不是会危及你健康的其他部分的事情。然后有些事情会更令人担忧,因为可能是恶性肿瘤或其他类型的事情。那么,这些类型的危险信号是什么?或者你是如何对可能导致听力损失的原因进行诊断的呢?你是如何一步一步地找出听力损失的根本原因的呢?2025年的诊断技术非常先进。我们可以观察毛细胞、外毛细胞、内毛细胞。我们可以观察听神经。我们可以观察中耳,即锤骨、砧骨、镫骨,耳膜。我们可以观察耳道,我们分别观察听觉系统的这些组成部分。当我们观察听觉系统时,这实际上涉及整个大脑。对于那些有风险的未经治疗的听力损失患者来说,他们的未经治疗的听力损失确实会加剧认知能力下降。现在,让我给你一些关于这方面的背景知识。当我们说某人有风险时,我们的意思是他们可能受教育程度较低。他们可能属于较低的社会经济群体。他们可能听力损失更严重。他们可能患有合并症,最重要的是糖尿病。当人们患有这些其他风险因素,并且未经治疗的听力损失持续8年、10年或12年时,他们患认知能力下降的风险更高。这在很长一段时间内的文献中都已得到证实。最近,几年前,约翰霍普金斯大学的ACHIEVE研究表明了这一点。风险最高的人认知能力下降的风险增加了约45%。然后,你在2017年、2020年和2024年发表的柳叶刀研究表明,你大约50%的痴呆风险是由于年龄和脱氧核糖核酸,你的DNA。但你另外50%的认知能力下降风险是由于大约14个可能改变的风险因素,而听力损失始终被证明是可能改变的风险因素中最重要的一个。我们已经谈到了认知能力下降。但是,患有未经治疗的听力和听觉问题的人也倾向于孤立、社会孤立、抑郁、焦虑,当然还有缺乏沟通。他们没有参与其中。这是一个非常困难的情况,因为你的听力损失使你更有可能感到孤独和孤立,并感到抑郁和焦虑。这帮助我们了解听力损失最严重的物理和精神健康后果是什么。没错。你能帮助我们识别听力损失的上游吗?当有人来到你的办公室,你已经诊断出他们,并且你说,“好吧,是的,这个人确实有一定程度的听力损失。”你是否试图了解为什么?为什么是这样?或者这仅仅是根据出现时的年龄,你就像,“好吧,这很可能是年龄相关的”,包括你的一些诊断?在某些人群中,你是否在考虑可能导致听力损失的其他因素?这是一个重要的讨论。当我们有70多岁、80多岁和90多岁的患者时,我们更能理解他们可能经历了巨大的噪音暴露,以及所谓的耳聋,这只是与衰老相关的听力损失。但这并不是说年轻人没有听力损失,因为在初等教育中,大约15%到20%的儿童在全面的听力学评估中会显示出听力损失。一只耳朵有听力损失或不对称的儿童更容易留级。老儿科医生过去常常说,“好吧,如果你有一只好的耳朵,你会没事的。”事实证明,这根本不是真的。如果你的孩子一只耳朵好,一只耳朵不好,那么你留级的可能性要高出约10倍。然后,当我们进入30多岁、40多岁、50多岁、60多岁等年龄较大的群体时,我们开始意识到,很少有听力损失的人会佩戴助听器。这与……助听器的污名有关,这是一个非常重要的因素。当FDA批准非处方助听器时,他们说这是由于获取和负担能力是导致非处方助听器的主要驱动因素。这些都是重要的驱动因素,绝对是的。但我作为一名听力学家,在我的40年职业生涯中一直认为,人们不寻求助听器的首要原因是没有人想佩戴它们。没有人想看起来像那个人。我讨厌这么说,尤其是一名听力学家,意识到化妆品是如此重要的驱动因素,这是一件可怕的事情。但是,当你看到隐适美,这是一种非常棒的牙套替代品,你看到隐形眼镜,数千万人佩戴,你开始理解,是的,你知道,这些东西的外观对所选择的东西有很大的影响。因此,我们现在有一些与旧款不同的选择。当你回顾2023年和2024年听力行业协会的统计数据时,你会发现非处方药并没有产生很大的影响。事实上,现在我们有了非处方药,我们中的许多人都预计情况会发生巨大的变化。好吧,它们没有发生变化。我认为造成这种情况的首要原因是它仍然是旧款的外形。大多数情况下,它是一种看起来像助听器的助听器,人们根本不想要它。在美国,大约90%的听力损失患者不佩戴助听器。因此,外形是一个……很重要的问题。像隐形耳道式助听器这样的隐形助听器,效果非常好。有些助听器是耳道式,效果也非常好。大多数助听器都需要定制。我们制作你的耳朵模型,我们将助听器安装到该模型中,然后它在美容方面相当有吸引力。它不显示出来。现在,FDA刚刚在2025年1月31日批准了一种新的外形,即Nuance Audio眼镜。我与该公司合作,需要声明一下。这些是时尚的眼镜,内置了你看不见的助听器。因此,对于许多人来说,这确实是一个有吸引力的选择,因为眼镜被认为是时尚的,人们……经常寻求的东西,他们想佩戴它们,而助听器几乎从来都不是人们想佩戴的东西。我作为一名听力学家讨厌承认这一点,但我告诉你,经过40年,我并不认为获取和负担能力是主要问题。我认为是外形。有60年代和70年代的研究表明,当人们佩戴可见的助听器时,他们看起来老了10岁,而且看起来能力较差。这不是对该行业的批评。该行业非常出色,他们在技术方面取得了令人难以置信的进步,但人们仍然不想佩戴它们。你的观点很好,即使它们更容易获得,人们也不一定会使用它们,因为他们可能会因为佩戴助听器而感到耻辱。但是,你是否担心有人可能会拿起助听器,感觉,“好吧,我听力好多了”,但他们掩盖了可能正在发生的其他事情?是的,这正是重点,当你获得一种没有专业人员参与的非处方助听器时,你可能会听到更大的声音,但你并不一定听到更清晰的声音。你在嘈杂的环境中听不到更好的声音。我最担心的是,人们会说,“好吧,我试过助听器,它们不起作用。”对于大多数人来说,我有消息要告诉你。当你尝试合适的、专业处方和安装的助听器时,它们会起作用。非处方药在技术上相当不错,但这里有一个关于它的问题。如果没有专业人员的指导,很难知道期望值、如何使用它们以及在哪里使用它们。对于视觉辅助器,当你得到一副10美元或15美元的眼镜时,你可以检查一下它们是否适合你。对于助听器,你做不到。这非常具有挑战性。如果你在2025年1月查看消费者报告,非处方助听器并不便宜。它们的价格在每对2000美元到3000美元之间,而我之前提到的眼镜助听器,每对的价格接近1100美元或1200美元。跟我们谈谈辅助设备干预的范围。我们开始讨论人工耳蜗的前兆。我们有助听器。跟我们谈谈你何时选择一个而不是另一个。这是一件非常重要的事情。人工耳蜗只适用于那些无法通过处方助听器改善听力的患者。你不想仅仅因为你看电视有困难就去植入人工耳蜗。这对任何人都不会有好结果。自1986年以来,人工耳蜗已获得FDA批准用于成人,自1990年以来已获得FDA批准用于儿童。初步来看,它们只适用于被认为是聋哑的人。我们所说的聋哑是指90分贝或更严重的听力损失。现在,如果你无法识别单词,你可以将人工耳蜗植入到中度严重的听力损失中。因此,如果你能够理解大多数谈话中至少一半的单词,那么你就不适合植入人工耳蜗。人工耳蜗非常出色。它们很棒,中等……我的导师Bill House博士实际上是世界上第一个在1959年、1960年进行人工耳蜗植入的人。他在洛杉矶做了三个。所以那是65年前的事情了。所以我们已经有了很长时间的人工耳蜗。但是大多数人都不适合。你提到了单侧,所以是单侧听力损失与双耳听力损失相同的人。那么,一个人患有单侧听力损失的原因与一个人双耳听力损失相同的原因是什么呢?单侧听力损失可能像耳垢堵塞一样良性,对吧?可能只是那只耳朵产生了很多耳垢,堵塞了你的耳朵。它也可能像脑肿瘤一样危险。有一种叫做听神经瘤的肿瘤,也叫做前庭神经鞘瘤,它最常表现为单侧听力损失或耳鸣。好吧,这真的很有帮助。因此,当我们考虑干预措施时,我们已经谈了很多关于助听器、辅助设备的事情。你能跟我们谈谈……保护机制?我们能做些什么来保护我们的听力?还有哪些其他生活方式干预措施可能会有益?保护听力的问题在于,这始终是一个个人的决定。大多数人会告诉你,他们没有暴露在很多噪音中。但我告诉你,仅仅是在展览厅或飞机上,你就会一直暴露在85或90分贝的声音中。我骑了50年的摩托车,大部分是哈雷戴维森,它们相当响亮。然后你还有拖拉机噪音、割草机、吹风机、吹叶机、修剪树篱机等。所有这些东西都非常响亮。你知道,你可以免费下载NIOSH,即国家职业安全与健康研究所。你可以在你的手机上获得他们的声级计,你可以检查一下东西有多响。超过85分贝的声音持续超过8小时会导致听力损失。这些是国家职业安全与健康研究所的指导方针。因此,我们必须非常小心,不要让自己暴露在非常响亮的声音中。音乐是另一个因素。但是大多数人会去音乐会或晚餐音乐会一两个小时。因此,他们有相当大的暴露,但通常是有限的。我更担心的是由于音乐造成的噪音暴露,而不是工业、军事或家庭……房主工具的暴露。我个人使用的是耳机。我是一位持照手枪拥有者,50年前我也在军队服役。所以我认为我对这些东西相当了解,但我仍然会在射击场佩戴护耳器。我认为对于那些整天暴露在大量噪音中的人来说,获得定制的护耳器非常重要。有一种叫做音乐家耳塞的东西。同样,我们制作你的耳朵模型。它们里面有声音过滤器,所以你仍然可以进行谈话,但它会消除最高和最低的光谱响应。这非常有用。这就是为什么音乐家会在舞台上佩戴它们的原因。你可以做很多事情。即使是那些小小的泡沫塞,小小的黄色泡沫塞,它们也很有效。它们的降噪等级通常超过20分贝。这非常重要,但前提是必须正确佩戴。大多数时候,它们没有正确佩戴。你必须做的是将它们紧紧地卷起来,将它们深深地插入你的耳朵里,不要造成疼痛。如果它很疼,显然不要这样做,但它应该深入你的耳道,然后它应该膨胀。然后,当你注意到你自己的声音质量发生了变化时,它可能就定位正确了。这很有趣。我想象一下,如果有人觉得他们有一定程度的听力损失,那么佩戴这种可能进一步降低声音质量的保护设备可能很难做到。这是你所经历的吗?当你这样说的时候,很难理解这一点,“好吧,我已经有中度听力损失了,所以我不会保护我的听力。”这很糟糕,因为当你患有听力损失时,你更容易遭受额外的听力损失。给我们举一些例子,说明你如何在下次预约时与你的医生交谈,以确保如果你担心听力损失,你能得到最好的评估和治疗。你知道,我认为说这些话真的很重要。“史密斯医生,我能听得清清楚楚。但是……在具有挑战性的倾听环境中,我很难理解。当我在家庭聚会上,当我在鸡尾酒会上,当我在餐馆里时,我听不懂人们在说什么。请确保我进行全面的听力学评估,包括言语和噪音测试,以便我们能够了解我在那种情况下的表现。然后,我会与听力学家或助听器销售人员合作来解决这个问题,因为市场上现在确实存在一些工具可以增强你在嘈杂环境中理解言语的能力。但如果我们只是让声音更大,那就不会奏效,因为这也会让噪音更大。这真的很有帮助。你提到有时只是有很多耳垢会导致听力问题。在你甚至去看医生之前,你会建议某人做些什么来真正优化他们的听力?好吧,正如听力保健领域的每个人都会告诉你的那样,你永远不应该使用棉签。坦白地说,大多数人实际上根本不需要清洁耳朵。你知道,最好的方法就是在淋浴时使用肥皂和水,然后用毛巾擦干。不要往里面塞任何东西。这非常危险。如果你犯了一个错误,并且弄伤了你的耳朵,你可能会终身患有前庭问题,这意味着你可能会无法控制地头晕。你可能会永久性听力损失。你可能需要手术来纠正这种听力损失。各种可怕的事情。你可能会终身患有耳鸣。我并不是为了吓唬人们才说这些话。我说这些是为了保护你的安全。不要往耳朵里塞东西。

Welcome to the WebMD Health Discovered Podcast. I'm Dr. Neha Bhatt, WebMD's Chief Physician Editor for Health and Lifestyle Medicine. Today, we're going to discuss hearing loss. If you've ever thought everyone around you is suddenly mumbling, or you've had trouble following conversations in noisy settings, or you're noticing a loved one has trouble tracking conversations when there's a lot of background noise, you

You're not alone. Hearing loss can sneak up on us at any age, often without obvious warning signs. For some of us, hearing loss may be caused by age-related degeneration. For others, it may be caused by consistent noise exposure, certain medications, earwax blockages, chronic ear infections, or even head trauma.

In this episode, we'll take a step-by-step approach to hearing loss and explore the telltale clues that might signal hearing trouble, the screenings and comprehensive tests available to us, and the surprising way hearing loss can affect mental and cognitive health over time.

We'll also break down the practical everyday steps to safeguard your ears, from understanding safe noise levels to recognizing when over-the-counter devices can help and when it's time for deeper assessment. We'll answer some of your most pressing questions like, is that slight hearing difficulty normal as we age? Or could it be hiding an underlying condition?

How can you advocate for yourself or your loved ones during medical appointments to ensure you get the right tests and solutions? But first, let me introduce my guest, Dr. Douglas Beck.

Dr. Beck is a distinguished audiologist with over four decades of experience in clinical, academic, and industry roles. Dr. Beck has held leadership positions at institutions such as the House Ear Institute, St. Louis University, and more, and has served as an editor for major audiology publications. An author with over 255 publications,

He's contributed extensively to audiology, cognition, hearing aids, and neuroscience research. He remains an active global lecturer, consultant, and writer, recently joining the Hearing Matters podcast in 2024 and Essilor Luxottica in December 2024. Welcome to the WebMD Health Discovered podcast, Dr. Beck.

Thank you. It's an honor to be here. Well, I am very, very excited to jump into our conversation. But before we do, I'd love to ask about your own personal health discovery, your aha moment around working with patients as it relates to hearing loss. My aha moment actually started at my fellowship in 1983 or 1984 at the House Ear Institute in Los Angeles. I had

I had the good fortune to be there a few years before the FDA approved cochlear implants for adults. That opened up my eyes to a lot of the neurophysiology and the technology that was about to emerge. And I was at the right place at the right time. And I was just so grateful to have been there. I am really excited to talk about all this entire range of options that are now available to patients. So thank you for kicking us off with that. But before we do, I'd

I'd love to take a step back and just start with the basics. People often think about hearing loss as something that's age-related. Can you talk to us a little bit about hearing loss in general, how we should be thinking about it? Is this really something that we need to start thinking about as we age? Or are there things that we should be thinking about throughout our entire lifespan?

Absolutely. That's such a great question because people rarely understand hearing loss. Hearing is just perceiving or detecting sound. And probably 90% of all people with significant hearing loss can hear. What they can't do is understand. What they can't do is comprehend sound. What they can't do is make sense of sound. So that gets us to the issue that there's

hearing and listening. Hearing is perceiving or detecting sound. Listening is making sense of sound. In the USA, we have about 340 million people. About one out of five of them has hearing loss. There's another 26, 28 million people in the USA with no hearing loss whatsoever.

but they have difficulty understanding, particularly in noise. So when we talk about hearing and listening, these two are intimately involved with each other and you can't really separate one from the other. Hearing is step one. You have to perceive sound, but the bigger task is for your brain to make sense of what you're hearing. Okay, so that's a really interesting distinction that I haven't necessarily thought of before.

I think most of us think about hearing assessments when our children are first born. We recognize that they sort of get this hearing assessment for what you have described as stage one. So the first piece of it, can they hear yes or no? And then we get these assessments during their early childhood as they're entering school. And then we don't necessarily think about assessments or questions

Are there varying stages of losing this ability to hear over the course of our life? And is that impacting our listening over the course of our life? So can you talk to us a little bit about common causes over the course of one's life where you might be at risk for hearing loss? Yes, this is such an important topic. Often in the U.S.A.,

Probably 97, 98% of all births get an immediate hearing test at birth. And that's done through a screening. And there are two types of screening. One is called otoacoustic emissions.

which is where we bounce some sounds off the eardrum and we measure the reflected sound. And then we can also do something called an auditory brainstem response. Again, we just put a little click in the ear and we measure the brain's response. That tells us that the patient or the child is hearing or not hearing. That's as much as it tells us. It doesn't tell us a lot of the detail there. What happens when you get into kindergarten or preschool or something like that, you might have a hearing test.

But those are just screenings. And the problem with the screening for hearing is that they do not test your ability to understand sound. They just say you're hearing or not hearing. And so that is not enough information to really make a good decision. Many children who cannot understand but can hear might have attention deficit disorder, attention deficit hyperactivity disorder, dyslexia. They might have all sorts of specific language impairments.

And speech and hearing problems often go hand in hand in young children. So the fact that a child passes a hearing test does not mean that he or she will be able to understand the teacher. What we do with tweening tests, it's very interesting how they've evolved. They are essentially looking for ear disease. You know, in children in particular, we're looking to make sure are both ears working and we're looking to see

In essence, you know, does that child have otitis media, a middle ear infection? Do they have a perforated eardrum? Do they have a lot of goo in their ear, which could be earwax, which is also called cerumen, and other physical ailments that relate to ears. But the interesting thing is, and this is in adults, only about 5 or 8% of all hearing loss is caused by a medical problem.

problem. Most of them go back to what you were addressing earlier. Age-related hearing loss, noise-induced hearing loss, ototoxic medications, head trauma. These are things that can cause hearing and listening difficulty.

But when we're screening, we're just really looking for a medical cause to a hearing loss. And honestly, I think we have to change that. I don't think screening in adults or children is appropriate. I think everybody should get comprehensive audiometric evaluation. That is actually what most insurers pay for. And in particular, Medicare actually calls it a comprehensive audiometric evaluation because we know that screenings are just not appropriate for people

who have signs or symptoms of hearing or listening disorders. Screenings are fine to the general population as long as they have no issues with hearing and no issues with listening. A hearing screening is much like a Snellen eye chart in vision. You know those charts

where you stand 20 feet away and you read the smallest line you can. That's useful. It tells you you can see or not see, but it doesn't tell you enough information about your actual visual acuity to make any good decisions about your visual health. So then tell me a little bit more about this comprehensive assessment that you're talking about. What does it entail and what is it going to tell you?

Yes, press the button when you hear the beat. That's a screening. That's not very useful. A comprehensive audiometric evaluation is what the American Academy of Audiology recommends. It's what the American Speech-Language Hearing Association recommends.

It's what the International Hearing Society recommends. What they do in these comprehensive audiometric evaluations is we do the press the button when you hear the beep, that's level one. But then we also do word recognition. We play digitized words into your ears one at a time. We record how well you hear in quiet.

But the reality is most people don't listen in quiet. You listen in noise, and that's where the problems come in. So all three best practice models, AAA, ASHA, and IHS say that you should be doing a speech and noise test. And we have calibrated speech and noise tests that tell us exactly how well or how poorly a person does in difficult, challenging listening situations like family gatherings, like

like cocktail parties, like restaurants. And these are, to me, as an audiologist, far more important than press the button when you hear the beep.

Again, the hearing is not the end all and be all. Listening means that you have heard it and that you can understand it. So if I have to pick between just hearing or just listening, I want a listening assessment because that tells me clinically how is the patient doing functionally? How are they doing in the real world? That to me tells me a lot more than the beeps. Okay, this is great and super helpful. So then I have two questions to follow up on that. So the first is,

Who buys themselves this type of assessment? Is this someone who's noticing, oh, I'm having some difficulty? Or is this something that you're saying should be done periodically throughout life?

And the second question is then at what frequency should these tests be done? The unfortunate situation is that most health care professionals, when they realize a patient is having hearing or listening problems, they'll say, oh, you should go get a screening. And that leads the patient to going and getting a screening. And then we still don't have enough information to speak thoroughly about what's going on with that individual.

I do believe that if I were to write the rules, which I have no power to do, but if I were to write the rules, I would say every child should have a hearing screening at birth, which again is very, very common now. That's called universal newborn hearing screenings.

They should have a comprehensive audiometric evaluation before they enter preschool or kindergarten or elementary school. And then I think if there's no signs or symptoms of any difficulty, they probably don't need it again for five years. But I'd like to see it done every five years. And I think for adults, most adults can't remember if they've ever had a comprehensive audiometric evaluation. What they do instead is they say,

things like this. Everybody mumbles. Have you ever noticed how all of a sudden everybody mumbles? People do not speak clearly anymore. When I was a lad, everybody had to learn to enunciate, you know, and then they'll tell you about selective hearing and all these other things.

And, you know, from their perspective, that is absolutely accurate. They will say people mumble. And from their perspective, absolutely accurate. But you know what's really going on? Is they're really not hearing the high frequencies because of noise-induced hearing loss or age-related hearing loss or ototoxic issues. Maybe they were on loop diuretics for a long period of time. Maybe they were on large doses of over-the-counter meds and it could be aspirin. It could be certain diuretics, antibiotics. And so what happens when

when we have these exposures is we tend to lose high frequencies first. Now there's some new information that's come out of Harvard in the last year or two that's really fascinating. The human ear, as we all know since World War II, really since Bonbeckershi, is that human hearing goes from about 20 hertz to 20,000 hertz.

So a couple of things to know when you're getting a hearing test on an audiogram that only goes from 250 to 8,000 Hertz. So what that means is you're not being tested on any of the notes below middle C on a piano. The entire left side of a piano is not represented on a hearing test further,

When somebody is born with hearing to 18 or 20,000 Hertz, we don't notice on an audiogram any hearing loss until it gets down to 8,000 Hertz. And by the time it's impacting 8,000 Hertz, you've theoretically already lost 10 or 12,000 Hertz, or you have hearing loss way above what's been tested.

And that leads to things like tinnitus. That leads to things like the inability to hear clearly in difficult, challenging situations. People think that both ears are the same and they should be, they should be symmetric. But here's the thing. If you and I were having a discussion right now, and you were one meter to my right ear, my right ear is hearing you at five, six, and 7,000 Hertz at those frequencies.

about 20 decibels louder than my left ear. And so it's very important that we hear all these sounds. That's how people understand what's going on in noise. That's how people are able to localize. That's how people are able to estimate distance based on the difference in loudness and the difference in timing between the two ears. And most people never give this any thought at all. But again, these, these are the reasons that we want to do speech and noise testing. These are the reasons we want to do extended high frequency testing.

These are the reasons that audiologists should be doing listening and communication assessments. And again, all of these are perfectly in alignment with the American Academy of Audiology, the American Speech-Language-Hearing Association,

and the International Hearing Society best practice recommendations. Now, unfortunately, only about 15 or 20% of hearing care professionals do that work because it is often limited by your insurance company. You know, they simply won't pay for it. And clinicians are always stuck in the same position. And I'm sure you are as a physician as well, where you know what you want to do, but you also know that the patient is stuck because their insurance won't pay for it. So we tend to do less

We order less than we might perfectly prefer to do. And so as a result, we're making decisions with less information available to us.

Just in what we've discussed so far, you've really helped us sort of identify some of the risk factors. So thinking about noise-induced, age-related, certain medications that might play a role. And you've also given us a really interesting sense of some of the signs or symptoms or red flags that we might be losing our hearing. So the thinking that everyone's mumbling, having this sort of difficulty in conversation with background noise. And you've

You've also gotten into what ideally should be done. So when you start suspecting these things or you start sort of describing some of these signs and symptoms, if you came to my office as a primary care provider, I would send you to audiology for further assessment. And you're saying that even there, people are not potentially getting that full spectrum assessment that they should. So can you talk one...

a little bit more about other red flags that I might have missed that I haven't mentioned, and two,

So how do we then have this conversation with an audiologist to ensure that we are getting that full spectrum of testing? There's a lot there to unpack. And I think the primary thing that we have to do is we have to say to audiologists, to dentists, to pediatricians, to otolaryngologists, do you practice in accordance with best practices by your national association? And virtually everybody wants to say yes.

But, you know, what that opens up the discussion to is, well, you know, we do what we feel we need to do. We let the signs and symptoms guide our testing protocols. And that's okay. But with hearing and vision, these are our two primary senses. And if we don't thoroughly examine them, we don't thoroughly know what's going on. So here's an interesting thing to think about with hearing and hearing loss.

When somebody has hearing loss, they have absolutely no way to know that. When you have vision loss, you can look at a newspaper and you realize you can't read it. You can look at your driver's license and realize you can't read it. You can look at your phone and you can't read it. With hearing loss, you have no way to know what you're not hearing. And if we don't test it comprehensively, nobody else knows what you're not hearing either. So I think that this is always a difficult, difficult situation because so

So much of healthcare is expensive. Getting vision tests, to getting dentistry, to getting orthopedic surgery, to getting brain surgery, everything is very expensive. So the question is, can we find a way to make sure that people who are having difficulty are availed of their diagnosis and then with their hearing care or their healthcare provider,

they can chart a path that's best for them. But it always starts with best practices because when we have best practices from any of the medical or healthcare disciplines, we know that these are very, very learned people who've looked at the literature, who've looked over the decades, if not centuries of data and said, this is what we need to do. Now to do less is sometimes more cost effective. I get that. But

I think that we have to make sure that we really have a diagnosis first and a treatment second. There's nothing new there. Diagnosis first, treatment second is always in the patient's best interest. So then talking a little bit more and digging a little bit more into the diagnosis piece of it, there are many different causes of hearing loss. Some one might consider benign. So this is not something that is going to endanger other parts of your health.

and then some that would be more concerning for potentially malignancy or other types of things. So what are some of those types of red flags or how do you sort of make a diagnosis on the spectrum of what could be causing your hearing loss? How are you making that step-by-step approach to figuring out what is underlying the hearing loss? Dr. Michael McKeown: Well,

Well, the diagnostics that we have in 2025 are very, very sophisticated. We can look at hair cells, outer hair cells, inner hair cells. We can look at the auditory nerve. We can look at the middle ear, which is the malignus incustapes, the eardrum. We can look at the ear canal, which we look at all of these components of the hearing system separately. When we are looking at the listening system, that actually involves the entire brain. For people with untreated hearing loss who are at risk,

their untreated hearing loss does tend to exacerbate cognitive decline. Now, let me give you a little bit of background on that. When we say somebody at risk, what we mean is that they probably have less education. They're probably in a lower socioeconomic group. They probably have more hearing loss. They probably have comorbidity factors, most importantly is diabetes.

And when people have these other risk factors going on and they have untreated hearing loss for eight or 10 or 12 years, they are at a higher risk of cognitive decline. And that's been shown throughout the literature for a long period of time. Most recently, the ACHIEVE study out of Johns Hopkins came out a few years ago, and they showed exactly that. People who were at the highest risk

had about a 45% increased risk of cognitive decline. And then you had the Lancet studies that came out in 2017, 2020, and 24, and they showed that about 50% of your dementia risk is due to age and deoxyribonucleic acids, your DNA. But the other 50% of your risk of cognitive decline is due to about 14 potentially modifiable risk factors, and hearing loss is consistently shown to be the number one potentially modifiable risk factor. So we've talked a little bit about

cognitive decline. But people with untreated hearing and listening problems also have a tendency towards isolation, social isolation, depression, anxiety, and of course, lack of communication. So they're not involved. And it's a very, very difficult situation because your hearing loss makes you more likely to be lonely and isolated and depressed and anxious.

It helps us sort of understand what are the consequences, the most significant sort of health consequences, physical and mental, of hearing loss. Exactly. Can you help us identify upstream of the hearing loss? What are you thinking about when someone comes to your office, you've diagnosed them and you've said, okay, yes, this person does have a certain degree of hearing loss. Are you trying to understand why?

why that is? Or is that just sort of based on the age at presentation that you're sort of like, okay, this is most likely age-related, including some of your diagnostics? Are there certain populations where you're sort of thinking about other things that might have caused the hearing loss? This is an important discussion. When we have patients who are in their 70s, 80s, and 90s, we have more of an appreciation that they've probably had tremendous noise exposure and something called presbycusis, which is just

a matter of hearing loss associated with aging. But that's not to say that young people don't have hearing loss because about 15 to 20% of children in primary education will show up on a comprehensive audiometric evaluation as having hearing loss. And children who have one ear hearing loss or an asymmetry are at a much greater risk of repeating a grade. The old pediatrician used to say, you know, that, well, if you have one good ear, you'll be fine. That turns out to not be true at all.

If you have one good ear and one bad ear in your child, you have about a 10 times greater likelihood of repeating a grade. So then once we get into the older folks in their 30s, 40s, 50s, 60s, et cetera, we start to realize that very, very few people with hearing loss will wear hearing aids. And that has a lot to do with

with hearing aid stigma, which is very much a factor. When the FDA approved over-the-counter hearing aids, they said it was due to access and affordability as the primary drivers for over-the-counter hearing aids. And those are important drivers, absolutely. But I've always thought in my 40 years as an audiologist that the number one reason people don't seek hearing aids is nobody wants to wear them. Nobody wants to look like that guy. And I hate to say that, particularly as an audiologist, and it's a terrible thing to realize that cosmetics are such an important driver.

But then when you look at Invisalign, which is a brilliant braces alternative, you look at contact lenses, which tens of millions of people wear, you start to understand that, yeah, and you know, the way these things look has a big impact on what is selected.

So now we have some options that are not the same old form factor. When you go back to the HIA, the Hearing Industry Association statistics from 2023 and 2024, you'll see that OTC did not make a big impact. In fact, now that we have OTC, many of us anticipated that things would change dramatically. Well, they haven't.

And I think the number one reason for that is it's the same old form factor. Most often it's a hearing aid that looks like a hearing aid and people just simply don't want that. About 90% of the people with hearing loss do not wear hearing aids in the USA. And so the form factor is

is a big deal. Hidden hearing aids like invisible in the canal, those do really well. There are some hearing aids that are canal fittings, those do really well. And most of those require a custom fitting. We take a cast of your ear, we build a hearing aid into that cast, and then it's fairly cosmetically appealing. It does not show. Now there's a new form factor just approved by the FDA, January 31, 2025, which is the Nuance Audio Glasses.

And disclosure, I do work with that company. And these are fashionable glasses that have hearing aids built in that you cannot see. And so that's really an attractive alternative for many, many people because eyeglasses are thought of as being fashionable and things that people...

often seek, they want to wear them, whereas hearing aids are almost never something that one wants to wear. And I hate to admit that as an audiologist, but I'll tell you after 40 years, I don't really think that access and affordability were the main problems. I think it was the form factor.

There's research out of the 60s and 70s that show when people wear visible hearing aids, they look older by 10 years and they look less competent. And that's not a slam on the industry. The industry is brilliant and they've made incredible technical advances, but people still don't want to wear them. Your point is well taken that even with them being more accessible and available, people don't necessarily use them because they might feel stigmatized because they're wearing this hearing aid.

But are you concerned that someone might just go pick up a hearing aid, feel like, okay, I'm hearing better, but they're masking something else that might be going on? Yeah, that's exactly the point, that when you're getting an over-the-counter hearing aid that has not involved any professional input, you may be hearing louder, but you're not hearing necessarily clearer. You're not hearing better in noise. My biggest fear is that people will say, well, I tried hearing aids, they didn't work.

I have news for most people. When you try appropriate, professionally prescribed and fitted hearing aids, they will work. It's the over-the-counter stuff that is pretty good technically, but here's the thing about this. Without professional insight, it's very hard to know the expectations, how to use them, where to use them. Now with visual cheaters, when you get a pair of glasses for $10 or $15, you can just check and see that they're working for you.

With hearing aids, you can't. It's very, very challenging. And if you go to Consumer Reports in January of 2025, the over-the-counter hearing aids, they're not cheap. They run between $2,000 and $3,000 a pair versus, you know, the eyeglass hearing aids that I was talking about earlier, which are closer to about $1,100 or $1,200 a pair. Talk to us a little bit about the spectrum of intervention for assistive devices. So we started our discussion with the precursors for cochlear implants.

We've got hearing aids. Talk to us about when you choose one versus another.

This is a very important thing. Cochlear implants are only for people who are not aidable through prescription hearing aids. You do not want to go get a cochlear implant just because you're having difficulty with the television. That's not going to work out well for anybody. Cochlear implants have been FDA approved for adults since about 1986 and for children since about 1990. Preliminarily, they were only for people who were considered deaf. And what we meant by deaf was a 90 decibel hearing loss or worse.

Now you can get cochlear implants down to a moderately severe loss if you cannot recognize words. So if you can understand at least half the words in most conversations, you're not a cochlear implant candidate. Cochlear implants are brilliant. They're wonderful, moderately

My mentor, Dr. Bill House, is actually the guy who did the first ones in the history of the world in 1959, 1960. He did three of them in Los Angeles. So that was already 65 years ago. So we've had cochlear implants for a long time. But most people are not candidates. So you mentioned unilateral, so one-sided hearing loss versus someone that has equal hearing loss in both ears. So

What would be a reason for someone having just one-sided hearing loss versus someone having hearing loss equally in both ears? One-sided hearing loss can be as benign as an ear full of wax, right? It could just be that that one ear produced a lot of wax as plugging up your ear. It could also be as dangerous as a brain tumor. There are tumors called acoustic neuromas, also called vestibular schwannomas, which most often show up as hearing loss or tinnitus on just one side.

Okay, that's really helpful. So when we're thinking about interventions, we've talked a lot about hearing aids, assistive devices. Can you talk us through...

protective mechanisms? Are there things we can do to protect our hearing? And are there any other sort of lifestyle interventions that might be beneficial? The thing about preserving your hearing is it's always a personal decision. Most people will tell you they have not been exposed to a lot of noise. But I will tell you that just in an exhibit hall or an airplane, you're exposed to 85 or 90 decibels of sound all the time. I drove motorcycles for 50 years, mostly Harley-Davidson's, and they're fairly loud.

And then you have things like tractor noise, lawnmowers, wind blowers, leaf blowers, you know, hedge trimmers. All of these things are very, very loud. And, you know, you can download for free NIOSH, which is National Institute of Occupational Safety and Health. You can get their sound level meter on your phone and you can check and see how loud things are. Anything over 85 decibels for more than eight hours will cause hearing loss. Those are the National Institute of Occupational Safety and Health guidelines.

And so we have to be very careful to not expose ourselves to tremendously loud sounds. Music is another one. But most people will go to a music concert or a dinner concert for an hour or two. So they've got substantial exposure, but generally it's limited. I'm less worried about noise exposure due to music than I am industrial or military or homeostatic.

homeowner tool exposure. So what I do personally is I use a headset. I am a licensed handgun owner and I was also in the military 50 years ago. So I feel like I'm pretty competent with that stuff, but still I will absolutely wear hearing protection whenever I'm at the shooting range. I think it's very important for people who are exposed to significant noise all day long to get custom made hearing protectors. There's something called a musician's earplug

Again, we take a cast of your ear. They have sound filters in there, so you can still have a conversation, but it knocks out the highest and the lowest spectral responses. And that's very, very useful. That's why musicians will wear those on stage. And there's all sorts of things you can do. Even those little foamy plugs, little yellow foamy plugs, they are very effective. They often have a noise reduction rating of better than 20 decibels.

And that's very substantial, but only if they're worn correctly. And most of the time they're not worn correctly. What you have to do is roll them up very, very tight, put them deep inside your ear, not to cause pain. If it's painful, obviously don't do it, but it should go deep within your ear canal and then it should expand. And then when you notice that your own voice quality has changed,

is probably positioned correctly. It's interesting. I imagine someone who feels like they have some degree of hearing loss then to sort of wear this protective equipment that

potentially diminishes the sound quality even more may be difficult to do. Is that what you've experienced? Yeah, it's hard to wrap your arms around that when you say, well, I've already got a moderate hearing loss, so I'm not going to protect my hearing. Well, that's a bad decision because when you have hearing loss, you are more susceptible to additional hearing loss.

Give us some examples of how you might talk with your provider at your next appointment to ensure that you get the best possible assessment and treatment if you're concerned about hearing loss. You know, I think it's really important to say things like this. Dr. Smith, I can hear you just fine. However...

I have a hard time understanding in challenging listening situations. When I'm at a family gathering, when I'm in a cocktail party, when I'm at a restaurant, I cannot hear or understand what people are saying. Can you please make sure that I get a comprehensive audiometric evaluation that includes

speech and noise testing so we can see how I do in that situation. And then I'll work with the audiologist or the hearing aid dispenser to solve that problem because there are specific tools that exist in the marketplace right now to enhance your ability to understand speech and noise. But if we're just making things louder, that's not going to do it because that will make the noise louder too. That's really, really helpful. You mentioned sometimes just having a lot of earwax can cause hearing problems. What

would you suggest someone does before they even get to that appointment to really optimize their hearing? Well, as everybody in hearing health care will tell you, you should never use Q-tips. And most people, frankly, never, ever need to have their ears cleaned. You know, the best thing to do is just soap and water in the shower

and then just dry it with a washcloth. Don't stick anything in there. It's very dangerous. If you make a mistake and you hurt your ear, you can have vestibular problems for the rest of your life, meaning you can be uncontrollably dizzy. You can have a permanent hearing loss. You might need surgery to correct that hearing loss. All sorts of terrible things. You could have tinnitus for the rest of your life. And I don't say any of these things to scare people. I say them to keep you safe. Do not stick things in your ear.

Thank you so much for being with us today. This episode was full of helpful information for anyone experiencing hearing loss. Some key takeaways for me include there's a critical difference between simply perceiving sound or hearing and fully understanding it, or what we normally think of as listening. And both need to be evaluated when assessing hearing health.

The standard hearing screenings we're most familiar with only measure whether you can detect sound, not how well you understand speech, especially in noisy environments. A full audiometric evaluation provides a more accurate picture of hearing ability.

We know that hearing loss has widespread impact on our lives that goes beyond difficulty in conversation. Untreated hearing issues can increase the risk of social isolation, depression, anxiety, and even contribute to cognitive decline. And most importantly,

early and ongoing preventive steps are key. Protecting our ears from loud noise and getting comprehensive hearing tests rather than relying on quick screenings can help catch problems early and preserve our listening ability for the long term.
