The Power of Probe Mic Measures (REM) in Fitting Hearing Aids
Hearing aids are incredible devices that can change the lives of individuals with hearing loss, enabling them to reconnect with the sounds and conversations around them. However, getting the most out of your hearing aids requires proper fitting. That’s where Probe Mic Measures, also known as Real-Ear Measurement (REM), come into play. In this blog post, we’ll explore what Probe Mic Measures are, why they’re crucial in hearing aid fittings, and why you should opt for a hearing healthcare provider like Flex Audiology that uses REM for fitting hearing aids.

What are Probe Mic Measures (REM)?

Probe Mic Measures, or Real-Ear Measurement (REM), is a technique used by audiologists to fine-tune hearing aids for an individual’s unique hearing needs. It involves placing a tiny microphone probe into the ear canal alongside the hearing aid. This probe measures the sound produced by the hearing aid while it’s in the ear, providing precise data about the amplification levels at different frequencies.

Why Are Probe Mic Measures (REM) Used?

1. Individualized Fitting

Everyone’s ears and hearing loss are different. Generic settings on hearing aids may not address your specific needs. REM allows audiologists to customize the settings of your hearing aids to match your unique hearing profile. Think of having access to a high end personalized equalizer stereo system.

2. Accuracy

REM is incredibly accurate, as it measures the actual sound levels reaching your eardrum. This ensures that your hearing aids provide the right amount of amplification at each frequency, maximizing your ability to hear and understand speech. 

3. Verification

REM serves as a verification tool to confirm that your hearing aids are working as intended. It helps audiologists fine-tune the aids to meet the prescription provided by your hearing evaluation. 

Why Shouldn’t Hearing Aids Be Fit Without REM?

Opting for a hearing aid fitting without Probe Mic Measures (REM) is like buying a pair of shoes without trying them on first. It’s a one-size-fits-all approach that doesn’t take into account the unique characteristics of your hearing loss and ear anatomy. Here’s why hearing aids should never be fit without REM:

1. Generic Settings May Not Work

Without REM, hearing aids are typically programmed based on general assumptions about hearing loss and using an average of 1000 ears. Your ear canal is as unique as a thumb print! This approach doesn’t guarantee that the aids will address your specific hearing needs effectively.   

2. Limited Benefits

You might not experience the full benefits of your hearing aids if they’re not accurately fine-tuned. This can lead to frustration and disappointment, as your hearing aids may not perform as expected. 

3. Potential Over-Amplification

Without REM, there’s a risk of over-amplification, which can lead to discomfort or even further damage to your hearing. Probe Mic Measures ensure that the amplification is precisely tailored to your needs, avoiding such issues.

How Will You Know If REM Has Been Done?

If you’re working with a hearing healthcare provider like Flex Audiology, they will typically inform you that REM has been performed during your fitting appointment. However, it’s always a good idea to ask and confirm. You might also notice some signs that REM has been done:

1. Improved Clarity

After REM, your hearing aids should provide clearer and more natural sound quality, helping you understand speech better.

2. Reduced Feedback and Distortion

REM helps eliminate feedback and distortion issues, resulting in a more comfortable listening experience.

3. Enhanced Comfort

With precise amplification, you should experience greater comfort when wearing your hearing aids for extended periods.

Making Your Decision

In the world of hearing aids, one size does not fit all.

To get the most out of your hearing aids, make sure they are fitted using Probe Mic Measures (REM). These measures ensure that your hearing aids are finely tuned to your unique hearing needs, providing you with the best possible listening experience.

If you’re considering hearing aids, choose a reputable provider that uses REM to ensure your hearing aids work optimally, helping you reconnect with the sounds and conversations you cherish. Don’t settle for anything less than hearing aids that are truly tailored to you.
