Real Ear Measurement
What the Probe Microphone Actually Measures
A real ear measurement in Glen Burnie, MD puts a thin probe microphone a few millimeters from your eardrum, so we hear what the hearing aid is delivering rather than what the manufacturer's first-fit software predicted. With live speech playing, Dr. Britney Ometz, Au.D. compares the sound arriving in your canal against the prescription target for your audiogram and adjusts until the two line up.

The Step Most Hearing Aid Fitters Skip
Verification is published best practice from the American Academy of Audiology, yet industry surveys put the share of fitters who perform it at roughly a third. Anne Arundel Audiology exists partly because of gaps like that one. Every hearing aid fitted here leaves probe-microphone verified, at the initial appointment and again whenever the prescription changes materially. It is standard practice here, not an optional add-on you have to ask for.
Real Ear Measurement FAQs
Questions about real ear measurement in Glen Burnie: what the probe microphone measures, how much time it adds to a fitting, whether it costs extra, and how a verified fitting differs.
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 putting at your eardrum. A soft silicone probe sits in the canal alongside the device while live speech plays, and the software graphs the result against the target curve calculated from your audiogram.
It matters because first-fit software is an estimate built on averages. Two people with identical audiograms can need very different settings, because ear canal length, volume, and resonance differ. Without verification you are trusting the average. With it, you are listening to a device tuned to your ear. Call 410-766-6320 to book a verified fitting in Glen Burnie.
The verification itself adds roughly 10 to 15 minutes per ear on top of the initial programming, plus a few minutes of conversation about what you are hearing as the curves move. Budget 60 minutes for the fitting appointment overall at our Crain Towers office.
That time earns its place. If high-frequency consonants are coming through sharp, or soft speech is landing below where you can hear it, Dr. Ometz can see the discrepancy on screen and correct it before you walk out rather than after two weeks of frustration. Appointments here are scheduled with room to do this properly. Call 410-766-6320 to find a slot.
Yes. Every hearing aid fitted at Anne Arundel Audiology includes real ear measurement verification at the initial appointment and any time the prescription is meaningfully changed. There is no premium tier, no separate line item, and no version of the fitting where it gets skipped to save time.
The same applies to devices you bought elsewhere and brought to us, and to follow-up visits years later, since hearing shifts and a device that hit target in 2023 may not today. Doing verification on every fitting is one of the clearest reasons patients report better outcomes here than at their previous provider. See how it fits into the process on our hearing aid fitting page.
A standard fitting typically ends where the manufacturer's software ends. The aid is programmed to a generic target derived from your audiogram, you are asked how it sounds, and you go home. Nothing has measured what is reaching the eardrum once the device is seated in your particular ear canal.
A verified hearing aid fitting closes that gap. With the probe in place, Dr. Ometz can see whether soft speech is audible, whether loud sounds are staying comfortable, and whether the feedback margin is safe, then adjust each band accordingly. The outcome is a device matched to your ear and your hearing loss rather than to an average. Call 410-766-6320.

“Dr Ometz had a very welcoming personality to this second time patient. I saw her for the utilization of a new device to remove excess wax from my ears...I wouldn’t hesitate to recommend her for an audiology evaluation and hearing aid devices if needed.”— Don T., Verified Google Review
