Scope Belt and Pulley noises

Using a scope and a delta pressure sensor (always a changing pressure vs an absolute pressure sensor reads live average) from Autoditex, and the stethoscope attachment from my Lisle stethoscope. The pulse sensors are piezoelectric sensors that detect change in pressure and/or vibration. Remember, noise is vibration!! Go try it! Thank you for watching!
