Calibration of audiometric bone conduction vibrators

A method of calibrating a bone conduction vibrator, comprising:

• providing an earphone coupler comprising a housing defining a cavity and an opening providing access to the cavity and a microphone for sensing sound pressure levels within the cavity;
• positioning a coupling member on the earphone coupler about the opening of the earphone coupler housing, the coupling member comprising an inner wall defining an aperture extending through the coupling member;
• positioning a bone conduction vibrator on the coupling member opposite from the earphone coupler with a vibrating member of the bone conduction vibrator disposed within the aperture of the coupling member in communication with the cavity of the earphone coupler;
• actuating the bone conduction vibrator;
• and
• sensing sound pressure levels generated by the bone conduction vibrator within the earphone coupler cavity with the microphone to determine if the bone conduction vibrator is generating desired vibrational force levels.

A bone conduction vibrator calibration system, comprising:

• an earphone coupler comprising a housing defining a cavity and an opening providing access to the cavity and a microphone for sensing sound pressure levels within the cavity and generating a corresponding electrical signal;
• and
• a coupling member positioned about the opening of the earphone coupler housing, the coupling member comprising
• a first surface in contact with the housing of the earphone coupler,
• a second surface configured to support the housing of a bone conduction vibrator above the opening of the earphone coupler housing;
• and
• an inner wall defining an aperture extending through the coupling member, the aperture configured to receive a vibrating member of the bone conduction vibrator.
