Baby heartbeat recording

We bought a baby microphone. It's still kinda early to be able to hear things clearly, but with patience we think we've been able to capture the sound of the heartbeat. It's faint, and not a studio quality recording... it actually sounds much much clearer in the provided headphones. I've increased the volume quite a bit to allow it to be heard, but you might want to turn your speakers up a bit. There are a couple of distortions (sharp crackles)... the heartbeat noise is much much fainter in the background.

According to the instructions, we're not really supposed to be able to hear it yet. As time goes on and the baby grows I hope the sounds will become clearer, and we should be able to distinguish kicks and hiccups and such... but that will have to wait.

For comparison, here's my hearbeat recorded with the same device.

UPDATE (Oct 3): I have a feeling the the baby heartbeat above is actually Tammy's. Apparently it's possible to pickup the mothers heartbeat on these devices from the placenta. Not sure... again, it's early... we'll try again and see if we can get better results.
