摘要
本文主要介绍电触听代偿仪的设计和研制。系统采用８０９８单片机及相关的模拟和数字接口电路实现了声音信号实时采集、处理及触觉编码输出等功能。初步实验表明：通过使用本系统，受试者在经过训练后，屏蔽听觉能分辨出环境中的不同警示声如门铃声、汽车喇叭声等，能感受到语音的节律，能帮助其判断声源的方向。
The present paper mainly introduced the development of electrotactileauditory substitution instrument which consists of 8098 single-chip microcomputer as well asperipheral analogue digital circuits to realize the realtime acoustic signal collecting,processingand electrotactile coding outptit. The results of preliminary experiment show that testermasked off hearing after training, with the aid of the instrument,can distinguish differentenvironmental sounds(such as alarm sounds,door-bell sound,automohile alarm sound and soon ),feel linguistic prosody and judge the directions of acoustic sources.
