前言目前一些研究小组正在研制直接对听神经输入电信号,以恢复全聋患者听觉的人工装置。通常要传递语言信息,这样一台人工装置一定要能刺激神经纤维不同的位置,其特征频率要和说话者越过声带的频率一样。
Introduction Some research groups are currently developing artificial devices that directly input electrical signals to the auditory nerve to restore the hearing of deaf patients. Language information is usually transmitted so that an artificial device must be capable of stimulating different positions of the nerve fibers at the same frequency as the speaker crosses the vocal cords.
