Abstract A bone conduction microphone for use in headset applications for Bluetooth and for radio, have been characterized. This has been done both in theory through simulations, and through experiments. The simulations were made by modeling the bone conduction microphone with electro acoustic analogous circuits. The simulations were run in MATLAB. Furthermore the response of the head to speech generated vibrations has been found through experiments. The bone conduction microphone has been improved by altering several aspects of the design. Frequency response and dampening of external noise have been tested on prototypes of the new design.
