The sensitivity of the EM172 is reported as 38 mV/Pa. Isn't that quite good=
?
My (limited and probably incorrect) understanding is that a 6dB change is r=
oughly twice as loud to the human ear, which I suppose makes sense since yo=
u're doubling the mic. Any idea how that would convert to equivalent sensit=
ivity in mV/Pa? I wouldn't imagine it would be 76 mV/Pa, would it?
Just trying to get a better understanding of how this works.
