REM Probe Tubes, 40 per Pack

These REM Probe Tubes are professional-grade accessories used in Real Ear Measurement (REM), also known as Speech Mapping — the gold standard method for verifying hearing aid fittings. Sold in a pack of 40 single-use tubes, they are designed for use with probe microphone measurement systems found in audiology and hearing aid dispensing practices, including Costco Hearing Aid Centers.

Each probe tube is a slender, flexible tube that is inserted into the patient's ear canal during a fitting session. The tip is positioned approximately 6 mm from the tympanic membrane, allowing the probe microphone to capture the exact sound pressure level that the hearing aid delivers at the eardrum. Proper placement depth is typically 28–30 mm. Single-use disposable tubes ensure hygiene between patients and accurate calibration for each session.

Real Ear Measurement using probe tubes is recommended by the American Speech-Language-Hearing Association (ASHA) and the American Academy of Audiology (AAA) as the preferred method for objectively verifying hearing aid performance. These replacement tubes are a routine consumable for any hearing care professional conducting best-practice fittings.
