Hi ,
I have to detect voice activity at a distance of 10m Omnidirectional detection.
What should be the sensitivity of the microphone to be used.

I conered on certain mic with sensitivities ranging from -48dbV/pa t0 -60dbV/Pa. only factor thet restricts the choice was IP65 certified microphones.
these are the choices I made.

Are my choices correct?? Are there better mics available??
