hello everybody
i want to use an electret condenser micophone for my project to detect the heart sound of a person!
the signal has to be amplified but in order to amplify it i have to know the range of the required amplification!

i do have an output target for the amplified signal but the problem is that i'm confused how to determine or calculate the range of output value of the microphone!
i have been told i should convert the value of the frequency response of the mic to volts!
is it the correct way!? if the way is correct, the obtained MAX & MIN values shoud be in AC right ?
finally if it's AC, is it Vp-p or Vp ??
