n. an audiometric test designed to supplement air-conduction testing. On its part, it further confirms whether the hearing loss previously detected occurs as a result of sensorineural problems or conductive factors. At controlled frequencies, it makes use of instruments such as a bone-conduction vibrator or oscillator. See air-bone gap.

BONE-CONDUCTION TESTING: "In bone conduction testing, a device called the oscillator is placed in contact with the mastoid bone of each ear."
