Recording heart sound

Can you record heart sound? If so, what equipment do you use?

There are some smartphone apps available and also electronic stethoscopes. I Googled “microphone for recording heart sounds” and got a bunch of returns.

@LDB, I understand there are ways to do it. I wonder who actually has experience with these.

I'm a retired sound guy, but that's one aspect of audio I've had no experience with at all.

There are different electronic stethoscopes available, or the Eko digital attachment works with any single tube stethoscope. A cheaper option is just a lapel mic with any stethoscope that has soft earpieces. I've used all three methods, while right now I just use a steth and lapel mic. I did recently buy an Eko attachment to play with too.

The Holter Monitor which is a portable device not that dissimilar to an EKG

Apart from that the standby Stethoscope with optional sound recording mics

I hate the Holter monitor, giant pain in the ass, they have new ones that are very small and stick on the skin for a week or so, then you bring it back in and they read the info.

Found a way to get a stethoscope earpiece to go over a lapel mic. So whenever I want to record I’ll just put that earpiece on the steth and it works beautifully.
