ABSTRACT:
Means and method of reducing the probability of false indications of microphone activity in a multimicrophone system incorporating means for sensing the activity of microphones.
The microphone, which is truly active, will receive its signal from its user before any of the other microphones receive the signal. The microphone circuit then sends a control wave to all of the other microphone channels reducing their amplifier's sensitivity and making them insensitive to false indication of activity.
