What does the muscle sound like?

I got a little side-tracked when analysing some EMG signals earlier. As the EMG signal is simply a wave, I thought (don’t ask me why) “I wonder what it sounds like”.

So…with the joys of MATLAB…here it is. This is 77 seconds of a muscle performing about five contractions (about 3 seconds long each) of increasing intensities.

Turns out…it sounds alot like a mixture of the wind and the tide rolling in and out.

I wonder how different muscles (with their different frequencies) sound. And whether the effects of fatigue (a change in the frequency component of EMG) can be noticed.
