This document describes a device that can be used to study acoustic and mechanical noise. The device contains a condenser mic and tone generator that can generate frequencies from 100 to 600Hz. It was used to test mechanical vibration transmissibility by placing three different sample holders - an aluminum plate, acrylic plate, and acrylic plate with a cut diaphragm - on the tone generator. Additional tests measured transmissibility using different piezo stage holders made of aluminum, polypropylene, and polypropylene with a rubber cushion.
