Real ear measurement and live speech mapping (REM/LSM) systems help hearing care professionals (HCPs) fit patients with hearing aids. Testing with real ear equipment ensures that the patient gets the proper amplification from their hearing instrument.
Real ear measurement systems measure the sound output of a hearing aid at the patient’s eardrum, taking the patient’s “real ear” characteristics into account. While REM and LSM are not required tests, it is recommended and can prove extremely beneficial for ensuring patients receive the perfect fit from their hearing aids.
