Yes, but this version has its own issues.

You can get an electronic stethoscope - I got ours from Science Kit & Boreal
Labs, but I'm sure other places sell them, too. It's a nice piece of work.
With an adaptor you can connect it to a set of speakers (I've found computer
speakers to be the best) and you broadcast the heartbeat. Pretty cool. A
favored demonstration is to have someone listen to their heartbeat, then
have them jump up and down/do jumping jacks/whatever, then listen again to
hear the change in the heartbeat.

The downside is that this contraption is good for a staffed demonstration,
but it's too fragile to leave out as an unmanned exhibit. And it costs a bit
over $250.

Does anyone know of anything off the shelf (or easily modified) so that
visitors can listen to their own heartbeat without putting typical
stethoscope ear pieces in their ears?

Many thanks,
