The audible heartbeat is from the valves closing.

Yeah! Maybe the OP has the heart sounds confused with a pericardial friction rub, which can happen in pathological states and is due to the heart sliding against the pericardium.

I didn't know there was a difference in terminology when I asked. This was a worthwhile question - I learned a lot.

Thanks for the great explanations!
