-28 dB at 1 kHz (0 dB=1V/Pa)
>80 dB at 1 kHz (1 Pa, A weighted)

5 VDC (3 to 10V)
600uA max at Vcc=3VDC
The EM172 ECM must be operated at or near its nominal operating voltage. Operation at too low a
voltage will produce excessive self-noise.
The BT-EM172 has a water-proof acoustically transparent seal. (black)
