Auditory Deprivation
The progressive deterioration in speech recognition ability in an unaided ear resulting from prolonged absence of acoustic stimulation.
Full Definition
Auditory deprivation refers to the phenomenon whereby an ear that receives insufficient acoustic input — either because a hearing aid is not worn, or because a person with bilateral hearing loss is fitted only unilaterally — experiences a measurable decline in speech understanding over time. The effect is thought to reflect central auditory system changes rather than peripheral cochlear deterioration. It is clinically significant when justifying bilateral hearing aid fitting and is documented in longitudinal outcome studies. Editors should not confuse auditory deprivation with auditory fatigue (temporary decreased sensitivity after noise exposure) or with reduced audibility due to unaided listening.
Usage
Usage note: Do not hyphenate as a noun phrase. Distinguish carefully from 'auditory fatigue' in clinical editing; they have different aetiologies and timeframes.
