AC-BC gap Audiology A normal finding in pure tone audiometry, in which the threshold for hearing sounds conducted through the air–air conduction, AC is lower than the threshold for sounds conducted through the bones of the
skull–bone conduction, BC; the relationship changes dramatically in conductive hearing loss, where the threshold for BC is lower than that for AC. See Pure tone audiometry.
