That's really cool... Is there any way to boost the power (or whatever you'd call it in a stethoscope) in the stethoscope? and are two microphones necessary?

I wonder if there is a way to notch filter out the noise, like I did on my voice for most of my songs.

I don't understand why you used two mics since stethoscope is a mono device. You just have to cut the stethoscope where it splits into two tubes and mount mic there.
