摘　　要：介绍了一种新型的声刺激器的设计方法。该声刺激器是以单片机 80 3 1为核心的单片机智能控制系统 ,它可发生短纯音、单周纯音、连续纯音、短声、滤波短声等各种声音信号。与传统的模拟型声刺激器相比 ,该声刺激器具有完备的 RS2 3 2通讯接口 ,及实时动态信号发生功能。通过系统软件控制声音信号的选择及发生 ,这种声刺激器既可以独立工作又可以与系统计算机联机工作。A kind of new design method about audiostimulator was introduced. This audiostimulator can provide short tone burst, single sine wave, continuous puretone, click, etc. To contrast with other old type audiostimulators, this audiostimulator has a standard RS232 interface and it can communicate with the system computer. This audiostimulator can be used by itself or by system computer. If it works with system computer, we can control it to choose sound signal type by system software. On the other hand, this apparatus can be easily developed into a common signal generator by some software changed .
