Abstract

A signal processor-based (DSP32C) stimulation system for cochlear implants has been developed. This system allows up to 14 stimulation channels (place principle) and conserves the time structure of the acoustic signal (periodicity principle). Any combination of these features is possible; in compressed analogue mode, pulsatile mode, or combinations of both. The system also takes electrical crosstalk into account caused by the electrical properties of the inner ear and compensates for it. Lateral inhibition strategies improve spatial resolution. Finally, the system offers an interface for the generation of quick continuous interleaved sampling strategies (CIS); up to 11,000 pulses/s per channel.

摘要

一种基于信号处理器（DSP32C）的人工耳蜗刺激系统已被开发出来。该系统允许多达14个刺激通道（位置原理），并保留了声学信号的时间结构（周期性原理）。这些特性的任何组合都是可能的；可以是压缩模拟模式、脉冲模式或两者的组合。该系统还考虑到了由内耳电特性引起的电串扰并进行补偿。侧向抑制策略提高了空间分辨率。最后，该系统提供了一个用于生成快速连续交错采样策略（CIS）的接口；每个通道每秒最多可产生11,000个脉冲。
