Real Ear Measurement in Wilmington & Southport, NC

Real ear measurement (REM) — also called probe microphone measurement — is the most accurate method available to verify that a hearing aid is programmed to deliver the correct amount of amplification for a specific person’s hearing loss and ear anatomy. It is the single most important step in ensuring your hearing aids perform at their best.

At Excel Audiology, REM is not optional — it is a standard part of every hearing aid fitting.

Why Real Ear Measurement Matters

Hearing aid fitting algorithms provide a starting point for programming based on your audiogram. But ear canals vary significantly in length, volume, and shape — and these differences affect how much sound actually reaches the eardrum. A device that’s programmed correctly on paper may be over- or under-amplifying in your specific ear.

REM takes the guesswork out of fitting. A thin probe microphone is gently placed alongside your hearing aid inside your ear canal. Sound is presented through a speaker, and the software measures exactly what your ear is receiving — at every frequency — in real time. Dr. Rickman then adjusts your hearing aid programming until measurements match your specific prescription target precisely.

What the Evidence Says

Multiple clinical studies show that hearing aids fit with real ear measurement deliver better speech clarity, reduce listening effort, result in higher patient satisfaction, and are more likely to be worn consistently.

Despite this, studies in the U.S. have found that fewer than 1 in 3 hearing aid fittings are verified with real ear measurement. At Excel Audiology, we hold ourselves to a higher standard — because our patients deserve nothing less.

What to Expect During REM

The process is straightforward and comfortable. A thin, flexible probe tube is placed in your ear canal alongside your hearing aid. You’ll listen to calibrated speech or tones played through a speaker in front of you, and the REM system captures what’s actually being delivered to your eardrum in real time. Adjustments are made on the spot until your prescription target is met.

Most patients are surprised by how quick and easy the process is — and many notice an immediate improvement in clarity.
