Diana Deutsch：从音乐家到音乐心理学家的转变，以及她对听觉错觉的研究，揭示了大脑在声音感知中的主观性和加工机制。她设计了双耳分听实验和音阶错觉实验，证明了大脑会根据经验和预期对声音进行重组和编辑，即使这些声音在物理上是相同的。她还研究了成长环境对声音感知的影响，例如不同地区的人对音调的感知可能不同。
Noam Hassenfeld：作为节目的主持人，他串联了整个节目的内容，并对听觉错觉和人工耳蜗等话题进行了深入浅出的讲解。他介绍了声音从声波到大脑感知的过程，以及大脑如何过滤掉一些声音信息，例如回声，以帮助我们更好地理解声音来源。他还讨论了大脑的“自上而下”加工过程，即大脑的预期和经验会影响声音的感知。
Matthew Wynn：作为一位听力学家，他解释了声音的物理特性以及声音在耳朵中的传递过程，包括外耳、中耳、内耳以及神经信号的传递。他还介绍了人工耳蜗的工作原理以及其对声音感知的影响，并指出人工耳蜗的成功很大程度上依赖于大脑的适应能力。
Mike Chorost：作为一位人工耳蜗使用者，他分享了自己逐渐失聪以及使用人工耳蜗后的听觉体验。他描述了人工耳蜗初期的声音感知体验以及大脑的适应性，并通过自己的经历说明了通过训练，人工耳蜗使用者可以重新学习将声音与意义联系起来。他还讨论了人工耳蜗对音乐的还原度较低的问题，以及他如何通过不断的调整和训练来改善自己的音乐欣赏能力。
Diana Deutsch: Her research on auditory illusions reveals the subjective nature of sound perception and the brain's role in processing auditory information. She designed experiments demonstrating how the brain reorganizes and edits sounds based on experience and expectations, even when the physical sounds are identical. Her work also highlights the influence of cultural background on sound perception.
Noam Hassenfeld: As the host, he connects the different aspects of the episode, providing a clear and engaging explanation of auditory illusions and cochlear implants. He explains the process of sound from sound waves to brain perception and how the brain filters out information like echoes to help us better understand sound sources. He also discusses the brain's 'top-down' processing, where expectations and experiences influence sound perception.
Matthew Wynn: As an audiologist, he explains the physical properties of sound and how sound is transmitted through the ear, including the outer, middle, and inner ear, and neural signal transmission. He also explains the working principles of cochlear implants and their impact on sound perception, noting that the success of cochlear implants largely depends on the brain's adaptive capacity.
Mike Chorost: As a cochlear implant user, he shares his experience of gradually losing his hearing and his auditory experiences after using a cochlear implant. He describes the initial sound perception experience with a cochlear implant and the brain's adaptability, and illustrates through his own experience how cochlear implant users can relearn to associate sounds with meaning through training. He also discusses the lower fidelity of music reproduction with cochlear implants and how he improved his music appreciation through continuous adjustments and training.
