bone conduction
Sound transmission pathway through skull vibration that bypasses the outer and middle ear structures.
Full Definition
Bone conduction refers to the transmission of sound vibrations through the bones of the skull directly to the inner ear, bypassing the outer and middle ear. In audiometric testing, bone conduction thresholds assess the function of the sensorineural mechanism specifically, helping differentiate between conductive and sensorineural hearing losses. Bone conduction hearing aids utilize this pathway for individuals with conductive hearing loss or single-sided deafness.
Usage
Usage note: Hyphenate when used as adjective (bone-conduction testing). Abbreviate as BC in technical contexts.
In Context
- "Bone conduction thresholds were within normal limits, ruling out sensorineural involvement." — Audiometric interpretation
- "The bone conduction hearing aid was recommended for congenital aural atresia." — Treatment recommendation
