Contact microphones!


Put simply, our eardrums and brain translates waves in the air into sound. Most microphones work in the same way; recording sound waves moving through air. But what if we want to listen to a sound from within an object? Contact microphones picks up the sound waves through the solid matter, not through the air around it. Contact microphones are often used with acoustic instruments, but can also be used for more experimental sound creations.

You can easily make your own contact microphone for a few dollars:
