Your mic setup

Good day!
I'm curious as to how everyone records their heart beat.

I'd like to get suggestions too on how to record using only my smartphone since my pc is out of commission.

Re: Your mic setup

Super basic here, literally just press my phone into my chest. If I need hands-free, I have a belt that I wrap around myself and slip my phone under that. Want to get an actual microphone eventually but even if I did I'm not quite sure how to get started with it. Like I know a lot of people create steth mics but.

Re: Your mic setup

I had a couple slightly different designs, the current favourite is: 4mm capsule mic from aliexpress (they are, like, a dollar for a dozen), thick-walled silicone tube from amazon, 4mm internal diameter, cable from an old headset or mic, and hot glue. https://drive.google.com/open?id=1mYBrF … OdaZPRGdPv

Re: Your mic setup

I use a lapel mic and slide it into the earpiece of a steth. Of course, it only works on soft earpieces, but it holds it in there very securely.

Re: Your mic setup

I use a stereo microphone with a thermal putty eg. Instantmold heat-formed around the two elements, with the stethoscope earpieces held firmly in place, shaping the putty around them until it cools. If done correctly this can allow the stethoscope to be removed and replaced as the stuff remains flexible.

Re: Your mic setup

I bought a cheap $25 cardio stethoscope, cut the tube at the Y-split and shoved the bare capsule of a disassembled cheap $3 desktop 3.5mm-jacked computer mic into the tube. The length of remaining tube makes it a little unwieldy, but it prevents air pressure distortion I ran into with attaching the mic straight to the end of the stethoscope head.
