Use our surface spy microphone wall probe to listen for faint sounds through virtually any solid surface. The probe features a built-in contact element and has an internal automatic gain control that does not require constant adjustment.
This microphone is designed to convert minute vibrations to voice band audio that can be received by headphones or secondary measurement equipment, so you can either listen to the audio via the included headphones, or record what you hear with any standard voice recorder.
