Vic Tandy:在十四世纪的古老建筑中,低频声波导致员工出现焦虑、抑郁、寒颤等症状,以及视觉幻觉(看到灰色人影)。通过研究发现,建筑物中的风扇产生的19Hz次声波与人眼共振频率接近,导致人眼震动,从而产生视觉幻觉。当风扇关闭后,症状消失。 播音员:次声波(infrasound)是低于人类听觉范围的声波,但它可以对人体产生影响。部分动物会利用18Hz左右的次声波来恐吓猎物,例如老虎在攻击前发出的咆哮声。18-20Hz左右的次声波被称为“恐惧频率”,因为它会对哺乳动物产生恐惧感,许多恐怖电影也利用这一频率来增强恐怖效果。大象、鳄鱼和长颈鹿等动物也会发出类似频率的次声波。火山爆发、闪电、雪崩等自然现象也会产生次声波。 “棕色音符”(brown note,5-9Hz)是一种假设的次声波,据说可以让人失去肠道控制,虽然没有得到证实,但一些实验表明,通过身体直接接触震动,低频次声波会对人体产生严重的负面影响,例如恶心、幻觉、呼吸困难等。居住在风力发电场附近的人可能会受到低频噪音的影响,出现头痛、失眠等症状。7Hz左右的次声波对人体最为危险,因为它与大脑的阿尔法节律和许多器官的共振频率相近,高强度下会直接影响中枢神经系统,可能导致恐慌、抽搐、呕吐,长期暴露甚至可能导致器官破裂和死亡。 历史上,许多文化都曾利用声音作为武器,例如凯尔特人的卡尼克斯乐器、维京人的袭击号角等。一些古代巨石建筑的建造可能使用了声波技术。超声波(ultrasound)也会对人体造成损害,例如加热细胞和气穴现象。美国海军曾利用超声波武器驱赶海盗。“哈瓦那综合症”是一种影响美国情报人员和外交官的神秘疾病,其病因可能是声波武器或高能微波。LRAD(远程声学装置)等声波武器已被用于人群控制,可能对人体健康造成损害。关于声波武器的研究和信息可能受到政府和公司的操控和影响。政府的研究结果可能不可信。

This podcast dives into the mysterious Havana Syndrome illness afflicting diplomats. We explore the strange world of infrasonic sound waves below the range of human hearing. These inaudible noises can induce anxiety or even sickness in people. 

What causes these bizarre symptoms? We uncover a range of natural and artificial sound sources that emit these creepy frequencies. From wind turbines to weapons, the effects are unsettling.

The story begins with a ghost hunt in a haunted lab. One scientist's quest to explain the paranormal leads to an unexpected discovery about sound. Tracing clues from here, things turn surreal as we enter the realm of acoustic specters and sonic warfare.  

Be prepared as we venture behind the veil of audible perception. Our journey reveals how sounds we can't hear still impact our minds and bodies in surprising ways. Havana Syndrome is just one mystery we'll attempt to demystify regarding the potent influence of creepy frequencies.
