An electronic device for multichannel cochlear implant is now available in case of total deafness and deaf-muteness. Any surgical technic of electrodes implantation may use this prosthesis. It consists in two parts, an outside package and an implanted receptor. The external device cut the sound in eight channels, whose frequencies correspond to those of the telephon bands. These eight sinusoidal waves are changed in pulses whose frequency and duration depend on the intensity of the initial signal. All these informations are multiplexed and injected in a high frequency wave to an antenna. Electromagnetic induction supplies through the skin the implanted receptor with power and informations. This receptor is preoperatively connected to the electrodes. With this device and with phoniatric training some speech recognition, and in case of deaf-mute patients voice improvement, may be obtained in some months.
一种用于多通道人工耳蜗植入的电子设备现已可供全聋和聋哑患者使用。任何电极植入的手术技术都可使用这种假体。它由两部分组成，一个外部组件和一个植入式接收器。外部设备将声音切割成八个通道，其频率与电话频段的频率相对应。这八个正弦波被转换为脉冲，其频率和持续时间取决于初始信号的强度。所有这些信息被多路复用并通过高频波注入天线。电磁感应通过皮肤为植入式接收器提供电力和信息。该接收器在术前与电极相连。使用这种设备并经过语音训练，在几个月内可能会实现一些语音识别，对于聋哑患者，还可能改善其发声。
