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.
