Developement of a custom measurement bench for passive radiators

28 August 2025

A passive radiator is a rigid membrane attached to a flexible suspension that radiates an acoustic wave when it vibrates…

The BU Series piezo-ceramic accelerometer has output from 20 Hz to above 10 kHz, and is used primarily as a contact microphone for high noise environments. It may also be used as an accelerometer with lightweight structures. As a contact microphone, the BU may be worn on the throat, or touching a bony part of the head (top, temple, or mastoid bone). BU has been integrated into helmet designs for radio communication for military and emergency services.
