Noise Sensing Microphone
The NSM assures the omnidirectional sound recording and pre amplification of the surrounding background noise. The 0 dB modulation is sent through the IDA4 System / IDA8 System in order to provide the automatic gain control feature of the A.N.G (Auto Noise Gain) component and allows the level adjustment where the NSM is implemented.
