Idea: Can we use two stethoscope microphone near the ear to use head sound as input.

Impossible to sleep when I had the idea ;)

So... if you put two stethoscope around the back of the ear. You should be able to hear and localise the sound of the organe in your head. And so to make a tool with the spectrometer that allows you to trigger action from your head without electric signal.

I really really really want to test it. But I can jump on a two months project randomly now. So I write it down.
