简介
一位双侧人工耳蜗植入者用 psychophysics 方法系统测试了自己的听觉极限，包括频率分辨、时间分辨和噪声中的语音感知。这为理解当前人工耳蜗的神经编码缺陷提供了罕见的第一手数据，对脑机接口和神经假体工程师有直接参考价值。
编辑判断
人工耳蜗是现存最成功的神经假体，但音乐感知和噪声环境语音识别仍是死穴。这位用户的自我实验暴露了一个关键工程盲区：现有电极阵列只能刺激约 22 个位点，而正常耳蜗有约 3500 个内毛细胞，信息带宽差距两个数量级。
对做多通道神经接口的团队来说，这提示了下一代高密度电极（如 Neuralink 的 N1 或 Paradromics 的 Connexus）需要解决的核心问题不是通道数本身，而是如何避免电极间串扰导致的感知失真。做语音 AI 的工程师也可以关注：当前 ASR 模型训练用的都是正常听力数据，人工耳蜗用户的畸变听觉输入可能是边缘场景鲁棒性的一个未开发测试集。

核心争论：人工耳蜗70Hz频率上限是硬限制还是感知/表述问题，及AI辅助科研写作的社区接受度
Author here. I'm Korean, and I have cochlear implants in both ears, which I received in a clinical trial in 2025. No one could tell me what I actually hear, so between 11 October and 4 November 2026 I ran seven psychophysical tests on myself (10,992 trials), using browser test apps that Claude built
A sort of anti HN comment to say but very interesting reading, I don’t know if I have answers to any of your questions but thank you for sharing, I will read more and consider it.
This was beautiful to read. Thank you for writing it! Don’t worry about it reading like slop - your voice comes through very distinctly to me. You mention a lot of ethics concerns; I am totally uneducated on medical ethics but I think those are pretty important questions. It doesn’t sound like you’v
