摘要：

目前治疗耳聋所依赖的助听器和人工耳蜗都要依赖聋人的听神经。课题组以往所申请的专利技术-“皮肤听声技术”就是利用皮肤感觉神经替代听神经来解决聋人的听声难题。文章介绍了一种 “皮肤听声”的新方法-“多通道阵列式皮肤听声技术”，用来解决聋人助听中语音分辨的难题。实验基于毛细胞的滤波原理，根据外界不同频率的语音信号，通过电子多通道带通滤波技术，将被转化为对应频率的电流信号，再通过电极阵列刺激皮肤的不同位置，使皮肤能够感知和分辨语音信号。实验对耳聋患者进行了响应声音信号的实验，通过语音频谱分析决定了带通滤波的频率点。结果显示皮肤感觉神经不仅可用来传递声音信号，而且可以用来分辨语音信号，说明皮肤神经很有潜力替代听神经用来解决聋人的听力问题。

Abstract:

The current use of hearing aids and artificial cochleas for deaf-mute individuals depends on their auditory nerve. Skin-hearing technology, a patented system developed by our group, uses a cutaneous sensory nerve to substitute for the auditory nerve to help deaf-mutes to hear sound. This paper introduces a new solution, multi-channel-array skin-hearing technology, to solve the problem of speech discrimination. Based on the filtering principle of hair cells, external voice signals at different frequencies are converted to current signals at corresponding frequencies using electronic multi-channel bandpass filtering technology. Different positions on the skin can be stimulated by the electrode array, allowing the perception and discrimination of external speech signals to be determined by the skin response to the current signals. Through voice frequency analysis, the frequency range of the band-pass filter can also be determined. These findings demonstrate that the sensory nerves in the skin can help to transfer the voice signal and to distinguish the speech signal, suggesting that the skin sensory nerves are good candidates for the replacement of the auditory nerve in addressing deaf-mutes’ hearing problems. Scientific hearing experiments can be more safely performed on the skin. Compared with the artificial cochlea, multi-channel-array skin-hearing aids have lower operation risk in use, are cheaper and are more easily popularized.
