real ear measurement
Objective verification technique measuring hearing aid output in the patient's ear canal during fitting.
Full Definition
Real ear measurement (REM) is the gold standard for verifying hearing aid fittings by measuring acoustic output directly in the patient's ear canal using a probe microphone. This technique accounts for individual ear canal acoustics and ensures the hearing aid provides appropriate amplification according to prescriptive targets. REM includes real ear unaided response (REUR), real ear aided response (REAR), and real ear insertion gain (REIG) measurements, which are essential for optimal hearing aid performance and patient satisfaction.
Usage
Usage note: Abbreviate as REM after first use. Use singular 'measurement' even when referring to multiple probe mic procedures.
