Accelerometers
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.
Features
• Voice intelligibility in a noisy environment
• Convenience of wearing (when integrated onto another worn article such as a helmet)
• Unobtrusive compared to a close talking boom microphone
• Waterproof and heat resistant
