Real Ear Measurement
How Probe Microphone Verification Works
Real ear measurement in Zionsville, IN places a soft probe microphone in your canal, a few millimeters from the eardrum, while your hearing aid is playing. Live speech runs through the device and Dr. Hughes reads what is actually reaching you against the prescription target calculated from your audiogram. Wherever the two lines separate, she adjusts gain frequency by frequency until they meet.

The Step Most Hearing Aid Fitters Skip
Real ear measurement is the published best-practice standard from the American Academy of Audiology and ASHA, yet industry surveys still put the share of fitters who perform it near 30%. Every hearing aid fit at Hughes Holistic Audiology is verified this way, at the first appointment and again whenever the prescription changes. It is part of the fitting rather than an upgrade, and it is much of why verified fittings outperform first-fit software.
Real Ear Measurement FAQs
Common questions about real ear measurement in Zionsville: what the probe microphone measures, how much time it adds to a fitting, and why first-fit software falls short.
Real ear measurement, also called probe microphone measurement or live speech mapping, is the only direct way to know how much sound a hearing aid is delivering to your eardrum. A thin, soft probe tube rests in the canal alongside the device while speech plays, and the software compares what arrives against the prescription target calculated from your audiogram.
It matters because ear canals are not interchangeable. Two people with identical audiograms can need noticeably different settings once canal size, shape, and resonance are accounted for. Without measurement you are trusting an average; with it, the gap gets closed before you leave the office. Call (317) 973-8098 to book a verified fitting.
The verification step runs roughly ten to fifteen minutes per ear on top of programming, plus a short back-and-forth about what you're hearing while the test is live. A fitting appointment at Hughes Holistic Audiology is scheduled for about an hour, and the measurement is built into that hour rather than tacked onto the end of it.
It is time well spent. If high-frequency consonants are coming through sharp, or soft speech is sitting below where it should, that shows on the screen instead of surfacing three weeks later as frustration. Adjustments are made while the probe is still in place, so you hear the corrected setting before you go home.
Yes. Every hearing aid fit here is verified with real ear measurement at the initial appointment, and again any time the prescription changes in a meaningful way. It is not a premium add-on or a separate line on your paperwork. It is simply how a fitting is done at this practice.
That standard holds across every brand on the shelf, whether your devices are ReSound, Signia, Phonak, or Oticon. National surveys have long put the share of fitters performing REM near 30%, which explains a lot about why two people with the same hearing loss can walk away with very different experiences of their hearing aids.
First-fit software makes an educated guess. It reads your audiogram, applies an average adult ear canal, and outputs a starting prescription. That is a reasonable place to begin, but research has repeatedly found first-fit settings land below target, especially in the high frequencies where consonants like s, f, and th live.
Those are the sounds that separate hearing speech from understanding it, which is why the difference shows up most in restaurants and group conversation. Measuring the output in your own ear and correcting toward target is what turns amplification into clarity. See how this fits into the appointment on our hearing aid fitting page.
A 45-Day Hearing Aid Trial, Not 30
Every set of hearing aids fitted at Hughes Holistic Audiology comes with a 45-day trial, longer than the 30 days most clinics offer. Thirty days is rarely enough time to adapt. Wear them where your life happens, at work, at the dinner table, and out around Zionsville. If they are not right, bring them back to be adjusted, exchanged for another model, or returned.

“My son was born with bilateral sensorineural hearing loss. After years of delivering that diagnosis, I sat on the other side of the chair and heard it. I opened this practice so patients get the appointment I would have wanted that day.”Dr. Jordan Hughes, Au.D., Owner
