Real-ear measurements, or REM, check what a hearing aid actually delivers inside your ear. They connect the prescription on a computer screen with the sound reaching you. If hearing aids seem loud but unclear, or have ended up unused in a drawer, verification is an important part of finding out why. It gives your audiologist objective information to use alongside your description of what sounds comfortable and useful.
Why Manufacturer First-Fit Software Guesses Fall Short
Hearing aid software uses your hearing test to suggest initial settings, often called a manufacturer’s “first fit.” This is a useful starting estimate. It cannot directly measure your individual ear canal, however. Every ear has its own shape, length, volume, and resonance. The same programmed hearing aid can produce different sound levels in two different ears, even when their hearing test results look similar. This distinction also matters when comparing OTC presets with professionally verified hearing aid fittings.
The dome or earmold also changes the result. A more open fitting lets sound escape differently from a closed fitting. Small differences in placement and acoustic coupling can affect how much amplification reaches the eardrum. A software screen that appears to match your prescription therefore does not establish that the actual sound in your ear matches it.
Too little amplification can leave important speech details difficult to hear. Too much in some areas can make sound uncomfortable. Simply increasing the overall volume may miss the underlying problem. Real-ear verification helps Dr. Erin Rushing identify which pitches and input levels need adjustment, instead of relying only on predicted output or a brief conversation in the fitting room.
How Real-Ear Measurement Works
After checking your ear canal, the audiologist carefully places a tiny, soft probe tube alongside the hearing aid. The tube connects to a measurement microphone and samples sound close to the eardrum; it does not touch the eardrum. This probe-microphone system allows the clinician to measure the sound levels being delivered while the hearing aid is in its actual wearing position.
You listen to recorded speech-like sounds through a speaker. Measurements at different input levels show how the hearing aid handles softer, conversational, and louder speech. Dr. Rushing compares the measured response with evidence-based prescription targets derived from your hearing evaluation. She adjusts the programming and repeats the measurements to check what changed.
The aim is appropriate access to speech while respecting comfortable loudness and output limits. Your feedback remains essential: mention sharp sounds, an unnatural own voice, or any discomfort. Measurement guides the fitting, but an individual’s hearing, device capabilities, and tolerance may require a carefully explained adjustment plan. REM is verification of amplification, not a promise of perfect hearing.
Keeping Hearing Aids Out of the Drawer
At Comprehensive Hearing Solutions, Dr. Erin Rushing performs Real-Ear Measurements during every new prescription hearing aid fitting. She can also verify and reprogram compatible hearing aids purchased elsewhere. Bring your current devices, charger or batteries, and any available hearing records. The first step is to check your hearing, ear health, device condition, and whether the practice can access the programming needed for your particular model.
An aid that is not helping may have a blocked wax filter, a poor physical fit, outdated settings, or a technical fault. It may also be unsuitable for your current hearing needs. Verification helps separate programming problems from other causes. When reprogramming is possible, measurements can guide changes and document the resulting output. Some proprietary or unsupported devices may limit the adjustments available.
Explain exactly why you stopped wearing the aids. Is speech unclear in restaurants? Are dishes painfully sharp? Does your own voice feel plugged? Those examples help prioritize the fitting and follow-up. The purpose is practical: make the devices more useful in the situations that matter to you, with clear expectations about what they can and cannot do.
Connect Verification with Ongoing Hearing Care
REM works best within a broader plan that includes diagnostic testing, discussion of communication goals, and follow-up visits. Speech-in-Noise testing evaluates a different question: how you understand speech with competing sound. Learn what happens during a hearing test to see why both sensitivity and speech understanding matter before choosing or adjusting devices.
After fitting, note which listening situations improve and which remain difficult. Fine-tuning, communication strategies, and auditory rehabilitation may all have a role. Arrange hearing aid fitting and programming in Houma to discuss a new fitting or an assessment of existing aids. A measured, individualized approach gives you a clearer basis for deciding the next step. Explore our prescription hearing aid options and learn why hearing and understanding speech are different.
