aided thresholds
Hearing sensitivity measurements obtained while the patient wears hearing aids or assistive devices.
Full Definition
Aided thresholds represent the softest sounds a person can detect while wearing properly fitted and functioning hearing aids or other amplification devices. These measurements are obtained using the same test protocols as unaided audiometry but with the hearing aids in place and functioning. Aided thresholds demonstrate the effectiveness of amplification across frequencies and help verify that hearing aid fittings meet prescribed targets. The difference between unaided and aided thresholds shows functional gain provided by the devices. Aided testing is essential for hearing aid validation and insurance documentation.
Usage
Usage note: Always use 'aided' as an adjective before 'thresholds'; contrast explicitly with 'unaided thresholds' when both are discussed.
In Context
- "Aided thresholds demonstrated improvement to within the speech range at all frequencies." — Hearing aid verification report
