摘　　要：以激光作为探测光源,基于双耳效应的原理设计了一套声源定位系统。该系统将由声音信号产生的振动通过激光反馈到接收器,并通过光敏二极管将其转化成电信号,放大后转化为数字信号,最终经过单片机数据处理显示结果。实验表明该系统能用于一定距离内的声源定位,可为听觉场景分析、仿生机器人等高新领域提供一定的研究基础。Based on the principle of binaural effect a localization system is designed for sound source using laser as the light source.Vibration generated by sound signal is fed back to the receiver via a laser.Then it is converted into an electric signal by the photodiode and converted into a digital signal after amplified.Finally the result is displayed through the singlechip processing data.Experiments show that the system can be used in sound source localization within a certain distance.It contributes to certain foundation of the research in such new areas of auditory scene analysis and biomimetic robots.
