How Real Ear Measurement Helps Hearing Aids Sound More Natural
Getting hearing aids is an important step toward hearing conversations, music, television, and everyday sounds more clearly. But simply choosing a quality hearing aid is not enough. How the device is programmed and fitted to your individual ears can make a major difference in how it performs.
One method hearing care professionals can use to verify hearing aid settings is called Real Ear Measurement, often shortened to REM.
Real Ear Measurement allows a hearing care professional to measure how amplified sound is reaching your eardrum while you are wearing your hearing aids. This information can be used to help fine tune the devices based on your hearing needs and the unique characteristics of your ears.
The result can be a more personalized hearing aid fitting that helps speech and other everyday sounds feel clearer, more balanced, and more comfortable.
What Is Real Ear Measurement?
Real Ear Measurement is a hearing aid verification method used to evaluate how much sound a hearing aid delivers inside a person’s ear.
During the procedure, a very thin probe microphone tube is carefully placed inside the ear canal. The hearing aid is then placed in the ear as it normally would be.
Your hearing care professional plays calibrated sounds through a speaker while the probe microphone measures the sound level close to your eardrum.
These measurements provide information about how your hearing aids are actually performing in your ears.
This is important because everyone’s ears are different. The size and shape of your ear canal can influence how sound travels through the ear.
Real Ear Measurement allows hearing aid settings to be evaluated using measurements taken from your own ears rather than relying only on software estimates.
Why Hearing Aids Do Not Sound the Same for Everyone
Modern hearing aids use sophisticated technology to process sound. However, two people wearing the same hearing aid model may have very different experiences.
There are several reasons for this.
- Every person has a different hearing loss pattern. One person may have difficulty hearing high frequency sounds, while another may have hearing loss across a wider range of frequencies.
- Ear canals also differ in length, shape, and volume. These physical differences can affect how amplified sound reaches the eardrum.
- Your hearing needs may also depend on your lifestyle. Someone who regularly attends meetings or social events may have different listening priorities than someone who spends more time in quiet environments.
This is why hearing aid fitting should be personalized.
How Real Ear Measurement Works
Real Ear Measurement is typically performed as part of the hearing aid fitting or verification process.
Here is what you may experience.
1. Your Hearing Needs Are Reviewed
Before making adjustments, your hearing care professional can review your hearing test results, listening difficulties, lifestyle, and communication goals.
This helps establish what your hearing aids need to accomplish.
2. A Small Probe Tube Is Placed in Your Ear
A thin, flexible probe tube connected to a microphone is carefully positioned in the ear canal.
The tube is designed to measure sound near the eardrum while your hearing aid is in place.
3. Your Hearing Aid Is Inserted
Your hearing aid is then placed in your ear normally.
This allows measurements to reflect how the device performs when you are actually wearing it.
4. Calibrated Sounds Are Played
Your hearing care professional presents controlled speech-like sounds or other calibrated signals through a speaker.
The probe microphone measures the amplified sound reaching your eardrum.
5. Results Are Compared with Prescriptive Targets
The measured hearing aid output can be compared with evidence-based fitting targets based on your hearing test.
If the hearing aid output does not closely match those targets, your hearing care professional can adjust the programming.
6. Your Hearing Aids Are Fine Tuned
Adjustments may be made to different frequency ranges and listening levels.
Measurements can then be repeated to verify the changes.
This process provides objective information that can complement your personal feedback about how the hearing aids sound.
How Real Ear Measurement Can Help Hearing Aids Sound More Natural
Many new hearing aid users need time to adjust to sounds they may not have heard clearly for months or years. Everyday noises can initially seem different or more noticeable.
A carefully verified fitting can help make this transition easier.
More Balanced Amplification
Hearing loss is rarely the same across every frequency.
You might need more amplification for certain high frequency sounds but much less amplification in other ranges.
Real Ear Measurement helps your hearing care professional evaluate whether amplification is being delivered appropriately across different frequencies.
This can contribute to a more balanced listening experience.
Clearer Speech
Speech contains sounds across a wide frequency range.
Some consonants, such as “s,” “f,” and “th,” contain important high frequency information. If these sounds are not audible enough, words can become harder to distinguish.
Real Ear Measurement can help verify that speech information is being amplified appropriately for your hearing needs.
The goal is not simply to make everything louder. It is to provide useful amplification where you need it.
More Comfortable Loud Sounds
A good hearing aid fitting also needs to consider comfort.
Sounds should be audible, but louder environmental sounds should not become unnecessarily uncomfortable.
Real Ear Measurement can provide information about hearing aid output at different input levels. Your hearing care professional can use this information along with your feedback when adjusting the devices.
A More Personalized Listening Experience
Hearing aid software can provide a useful starting point based on your hearing test.
However, software predictions cannot fully account for every individual’s ear canal acoustics.
Real Ear Measurement adds information from your actual ear.
That additional information can help create a fitting that is more closely matched to your individual hearing needs.
Real Ear Measurement vs. Manufacturer First-Fit Settings
When hearing aids are first programmed, fitting software may generate recommended settings based on your audiogram and a fitting prescription.
These settings are often called first-fit settings.
First-fit programming can provide a starting point, but predicted hearing aid output and the sound actually reaching your eardrum may not always be identical.
Real Ear Measurement allows the hearing care professional to check the actual output inside your ear.
Think of it as the difference between estimating and measuring.
Software predicts how the hearing aid should perform. Real Ear Measurement helps verify how it is actually performing in your ear.
Why Hearing Aid Verification Matters
Hearing aids are highly personalized medical devices. Their performance depends not only on the technology inside them, but also on how appropriately they are selected, fitted, programmed, and verified.
Verification provides objective information about whether hearing aids are meeting prescribed amplification targets.
This is especially important because hearing aid users cannot always identify which frequencies need adjustment.
You may simply notice that conversations are difficult, voices sound unclear, or certain sounds feel too strong.
Objective measurements combined with your real-world feedback can give your hearing care professional more information for making appropriate adjustments.
Is Real Ear Measurement Uncomfortable?
Real Ear Measurement is generally a straightforward procedure.
The probe tube used during testing is very thin. You may notice the tube being placed in your ear canal, but the procedure should not be painful.
Your hearing care professional will position the probe carefully and make sure it is appropriately placed before completing the measurements.
The procedure does not require surgery or needles.
If you have questions or discomfort during any part of the process, tell your hearing care professional.
Does Real Ear Measurement Mean Hearing Aids Will Sound Perfect Immediately?
Not necessarily.
Real Ear Measurement can help verify that your hearing aids are providing appropriate amplification, but your brain may still need time to adjust to hearing sounds again.
If you have lived with hearing loss for a long time, everyday sounds may initially seem unfamiliar.
Your own voice may sound different. Dishes, running water, footsteps, or environmental sounds may seem more noticeable than you remember.
This does not automatically mean something is wrong with your hearing aids.
Your hearing care professional can explain what to expect during the adjustment period and determine whether additional programming changes are appropriate.
Follow-up care is an important part of successful hearing aid use.
When Should Hearing Aid Settings Be Rechecked?
You should consider talking with your hearing care professional if you notice significant changes in how you hear with your devices.
For example, you may want to schedule a follow-up appointment if:
- Speech has become harder to understand
- Your hearing aids consistently sound too loud or too soft
- Certain sounds are uncomfortable
- You are struggling in environments where you previously heard well
- Your hearing has changed
- You have received new hearing aids or significant programming changes
Regular hearing evaluations are also important because hearing can change over time.
If your hearing test results change, your hearing aid programming may need to be reviewed as well.
Real Ear Measurement Is Only One Part of a Successful Hearing Aid Fitting
Real Ear Measurement provides valuable objective information, but successful hearing care involves more than a single measurement.
A comprehensive approach may include a hearing evaluation, appropriate hearing aid selection, personalized programming, verification, counseling, follow-up visits, and ongoing adjustments when needed.
Your experience matters too.
Tell your hearing care professional where you are having difficulty. Be specific about situations such as restaurants, family gatherings, meetings, television, telephone conversations, or outdoor activities.
Combining objective measurements with your everyday listening experiences can help your hearing care team make more informed adjustments.
