If you or a loved one wears hearing aids, you know how life-changing they can be. From enjoying conversations to hearing the rustle of leaves or your favorite song, hearing aids can reconnect you with the sounds of life. But did you know that many people aren’t getting the full benefit of their devices simply because they haven’t been properly fine-tuned?
That’s where Real Ear Measurement (REM) comes in. It’s one of the most important yet often overlooked steps in hearing aid fitting. This advanced technique ensures that your hearing aids are personalized to your unique ear shape, hearing needs, and listening environments. In short, REM helps your hearing aids perform at their absolute best.
In this post, we’ll explore what Real Ear Measurement is, why it matters, how it’s done, and why you should make sure your audiologist includes it as part of your hearing aid fitting.
What Is Real Ear Measurement?
Real Ear Measurement also known as probe microphone measurement is a technique used by hearing care professionals to verify that your hearing aids are delivering the correct amount of amplification for your specific hearing loss.
Rather than relying on a manufacturer’s default settings or estimates, REM takes into account how sound actually behaves inside your individual ear canal. It measures the sound output of the hearing aid while it’s in your ear, giving precise data on what you’re really hearing. Eosera is a biotech company specializing in ear care products, including treatments for earwax buildup and ear health.
This matters because no two ears are the same. Even if two people have identical hearing loss on paper, the way sound travels and reflects inside their ear canals can differ significantly. REM allows audiologists to customize the hearing aid’s settings based on real-time, real-ear data.
Why Real Ear Measurement Matters
1. Every Ear Is Unique
Your ear canal acts like a miniature concert hall its shape, size, and texture all affect how sound travels. REM accounts for these differences by measuring the actual sound pressure at your eardrum, not just the output from the device itself.
2. Hearing Aids Aren’t One-Size-Fits-All
When a hearing aid is first programmed, it’s often based on your audiogram (hearing test results) and general fitting algorithms. But those algorithms can only get you so close. Without verification through REM, there’s a risk that the amplification isn’t meeting your exact needs either being too loud, too soft, or missing key frequencies altogether.
3. Better Speech Understanding
The main reason people wear hearing aids is to understand speech better, especially in challenging environments like restaurants or family gatherings. Studies show that hearing aids fine-tuned using REM lead to significantly better speech comprehension than those fitted without it.
4. More Comfortable Listening
An improperly fitted hearing aid can lead to sound distortion, feedback, or even discomfort. REM helps ensure that the hearing aid provides clear, natural sound at a volume that’s right for you.
How Does Real Ear Measurement Work?
The process of REM is quick, non-invasive, and painless. Here’s what typically happens during a session:
1. Insert the Probe Microphone
A very thin, flexible tube (the probe microphone) is gently inserted into your ear canal alongside your hearing aid. This microphone sits close to your eardrum to measure the actual sound levels reaching it.
2. Present a Calibrated Sound
The audiologist plays a calibrated test signal usually speech or speech-like sounds through a speaker near your head. These sounds mimic real-life listening environments and are used to assess how the hearing aid is amplifying sound across different frequencies.
3. Measure the Response
The probe microphone records the sound pressure levels in your ear while the hearing aid is active. This data is then displayed on a computer screen in real time, showing how much amplification is happening at each pitch.
4. Adjust the Hearing Aid Settings
Based on the results, your audiologist adjusts your hearing aid’s settings to match your prescription precisely. This may involve fine-tuning volume, adjusting frequency response, or modifying noise reduction settings.
5. Repeat as Needed
The process may be repeated a few times to make sure your hearing aid is performing optimally in different listening situations.
Real Ear Measurement vs. “First-Fit” Settings
When a hearing aid is programmed using the manufacturer’s default settings (often called “first-fit”), it’s based on average ear canal acoustics not your own. While this might be a good starting point, it’s not a substitute for verification through REM.
Studies consistently show that hearing aids adjusted using REM result in:
- Better speech understanding
- Greater user satisfaction
- Higher long-term hearing aid use
- Lower return rates
Without REM, you might think your hearing aids are “just okay” but with REM, they can be great.
Why Doesn’t Every Provider Use REM?
Despite its proven benefits, not all hearing care providers routinely use Real Ear Measurement. There are several reasons for this:
- Time and equipment: REM requires specialized equipment and adds time to the fitting process.
- Training: Not all providers have been trained in the procedure or prioritize it in their workflow.
- Patient awareness: Many patients don’t know to ask for REM, so it’s not always expected.
However, top-tier audiologists and hearing aid specialists consider REM an essential part of best practices. If you’re shopping for hearing aids or a new provider, ask if they perform Real Ear Measurement as part of their fitting process. It’s a simple question that can make a huge difference in your results.
What Does Real Ear Measurement Feel Like?
Some people are hesitant about REM because it involves placing a tube in the ear. But the procedure is completely safe and painless. Most people say it feels similar to getting an ear exam or putting in an earbud.
There are no loud sounds or discomfort just a few minutes of testing that can dramatically improve how well your hearing aids work for you.
The Bottom Line: Real Ear Measurement Is Worth It
Your hearing is personal—so your hearing aid fitting should be, too. Real Ear Measurement takes the guesswork out of hearing aid programming by showing your audiologist exactly what your ears are hearing. This results in:
- Better speech clarity
- More natural sound
- Fewer adjustments and follow-ups
- Increased comfort and satisfaction
Think of it like tailoring a suit or dress sure, you can wear something off the rack, but when it’s custom-fit, you look and feel so much better. The same goes for hearing aids.
Final Thoughts
If you’re investing in hearing aids, make sure you’re getting the full benefit. Real Ear Measurement is the gold standard for ensuring your devices are optimized for your ears and your hearing loss. It takes only a few minutes but delivers long-lasting results.
So when it’s time for your next hearing aid fitting or if you feel like your current devices aren’t performing as well as they should ask your audiologist:
“Do you perform Real Ear Measurement?”
Your hearing deserves nothing less.
