Trying to Record Heartbeat

I am trying to make a recording of my heartbeat and am getting frustrated by no success. First of all, the microphone I bought is small, but still too big to fit in the tubing without cutting it. It was the best small mic I could find, the rest were all boom mics, which I figured would not work. The quality is so-so, so but if I talk or sing it works find. I'm using aud macity to record. No matter how I attach the mic to my steth- shoving it in the earpiece, cutting off the end of the tubing and shoving it in, it won't work. Now it could be that the mic I bought is not sensitive enough to pick up the sounds, but yet it manages to pick up the TV across the room just fine. It was originally a mic attached to two ear buds, but I cut off one of the buds to be able to easily shove the mic in places. Any ideas/suggestions? I couldn't find a mic in the first place I had to go to six different stores before I found one at Office Depot.

Did you try holding the microphone against your chest without using the stethoscope?

I did, I could try that again...

What I did was detach the headset from the stethoscope and heavily tape the tubing directly onto the mic. The trick is to make it as airtight as possible. The same trick more or less applies if you push the mic directly into your chest. If you have some way to 'trap' the sound, like if you lie face down on top of your mic or something, it should work better. I've got other ideas/tips as well, if you're still having trouble feel free to send me a PM.

Peaches i am having the same problems and have been for a long time. Pepito thanks for the tips Bro I will try those out.

I ended up getting it to work through my webcam mic. I couldn't hear anything in Audacity while doing it, but while chatting with a friend I just put the mic (which is built into the camera) on my chest and he said he could hear it perfectly.

Good to hear you were able to get it to work! 😄

I think there are youtube videos on how to correctly set up a mic. Need quite a few accessories !
