What Is Real Ear Measurement? A Guide To Accurate Hearing Aid Fitting

Are you looking for a way to get an accurate hearing aid fitting? The real ear measurements might be just the thing for you! In this article, we'll discuss what it is and how it can help you get the most out of your hearing aids. We'll also look at the pros and cons of this method and compare it with other alternative methods. Read on to learn more about real ear measurements!

What Is Real Ear Measurement?

Real ear measurement (REM) is an objective way to measure how well a hearing aid is amplifying sound at the eardrum. It is generally considered the gold standard for hearing aid fittings, as it provides a more accurate representation of how the hearing aid will perform in real-world listening situations.

There are two main types of REM: static and live. Static REM uses a probe tube to measure the sound pressure level at the eardrum, while live REM uses a microphone to measure the actual sound that the person with hearing loss is hearing. Live REM is generally considered to be more accurate, as it takes into account variables such as resonance and occlusion.

REM can be used to fit any type of hearing aid, including behind-the-ear (BTE), in-the-ear (ITE), and completely-in-the-canal (CIC) styles. The procedure is relatively quick and painless, and can usually be done in one or two visits to the audiologist.

Why is Real Ear Measurement Important?

There are a few key reasons why real ear measurement is important for hearing aid fitting:

It ensures that the hearing aid is properly calibrated to the individual’s hearing loss.

It allows the audiologist to fine-tune the settings of the hearing aid to match the person’s unique listening needs.

It allows for verification that the hearing aid is providing the expected benefit to the individual.

It can help identify potential problems with the fit or function of the hearing aid, which can then be addressed.

Overall, real ear measurement is an important part of the hearing aid fitting process and helps ensure that people with hearing loss can get the most out of their hearing aids.

How Is Real Ear Measurement Done?

There are three primary components to real ear measurement: the probe tube, the tympanometer, and the sound source. The probe tube is inserted into the ear canal and positioned just past the eardrum. The tympanometer is then used to measure the pressure in the ear canal. The sound source is used to generate a low-frequency tone that is fed through the probe tube. This tone is used to assess how well the eardrum and middle ear are functioning.

Benefits of Real Ear Measurement

If you’re considering purchasing a hearing aid, you may have heard of real ear measurement (REM). While it may sound like a complicated, technical process, REM is simply a way to ensure that your hearing aid is set to your specific hearing needs. 

Here are some benefits of having REM done when you get your hearing aid:

You’ll be able to hear better in all environments, not just in quiet places.

Your hearing aid will be less likely to give you a “plugged up” feeling.

You’ll be less likely to experience feedback from your hearing aid.

Your hearing aid will be more comfortable to wear because it will fit your ear canal perfectly.

You’ll have peace of mind knowing that your hearing aid has been customized specifically for you and your unique hearing needs.

You’ll understand the settings your audiologist has programmed into your hearing aid better, allowing you to make more informed decisions when adjusting the settings on your own.

Risks Associated with Real Ear Measurement

There are several risks associated with Real Ear Measurement (REM) that audiologists need to be aware of. First, REM can be painful for some patients. Second, the use of a small probe in the ear canal can cause damage to the ear if not done correctly. Third, REM can sometimes produce false positive results, leading to unnecessary hearing aid fittings. Finally, REM is time-consuming and requires specialized equipment, which can make it difficult to perform in some settings.

Real Ear Measurement is an important tool for ensuring accurate hearing aid fitting. It allows audiologists to measure and monitor the output of a hearing aid to make sure it is providing the best possible amplification for each user. Real ear measurement can also be used to identify any potential issues with a hearing aid, such as feedback or improper fit, enabling audiologists to take corrective action more quickly and easily. With real ear measurements, you can rest assured that your hearing aids are providing optimal sound quality and maximum comfort.
