If one hearing aid suddenly seems quieter, tinny, or less clear than its partner, everyday conversations can start to feel lopsided. Hearing aids are designed to amplify sound in a way that feels natural, so a difference between them should be examined.
At HEAR Ontario, our team of audiologists and hearing instrument specialists can check your hearing and devices to help determine whether the difference comes from maintenance needs, programming, fit, or a change in your ears. Most clients can start troubleshooting at home, then visit one of our clinics if the difference persists.
Is an Uneven Pair of Hearing Aids Ever Normal?
An uneven pair of hearing aids can be normal, because your ears may have different degrees or patterns of hearing loss and each device may need a different amount of amplification. A difference between hearing aids does not automatically mean one is broken. Ear canal shape and earpiece fit also affect the sound that reaches your eardrum.
The goal is comfortable, useful hearing across both ears. Matching the volume numbers or programming exactly may not achieve that goal. One ear may need more help with higher-pitched speech sounds, so the settings on that hearing aid may need to be different from the other.
However, a new or worsening imbalance deserves attention. Earwax, a blocked filter, moisture, or a damaged component may reduce output on one side. Hearing changes can also make settings that were previously appropriate feel uneven.
What Does It Sound Like When One Hearing Aid Isn’t Keeping Up?
When one hearing aid isn’t keeping up, that side may seem softer, speech may sound muffled or tinny in that ear, or the device may whistle, crackle, or cut out. Describing the difference clearly helps narrow down the possible cause. Pay attention to whether it affects speech, your own voice, background noise, or streamed audio. Clients often describe these experiences:
- One side seems louder or softer during conversation.
- Speech sounds muffled, sharp, tinny, or distorted in one ear.
- Your own voice sounds hollow or unusually loud on one side.
- One device whistles, hisses, or crackles intermittently.
- Sound cuts out in one hearing aid.
- Phone calls or music sound uneven while everyday conversation sounds balanced.
Whistling may result from a poor fit, wax, or a device problem. A plugged-up sensation with your own voice may relate to how the earpiece seals the ear canal. Hissing may reflect amplified environmental sound or noise generated within the device.
These descriptions are clues, not diagnoses. A louder hearing aid doesn’t necessarily mean clearer speech, and two devices can sound different even when both work. Note when the problem began and which situations make it most noticeable.
Which Home Checks Help When Your Hearing Aids Sound Different?
The home checks that help most when your hearing aids sound different are confirming power and mute settings, the listening program and volume, the battery or charge, the fit, and the wax filter. Start in a quiet room and check one possible cause at a time before making further changes. Follow the instructions for your model:
- Confirm each hearing aid is on and has not been muted.
- Check the selected listening program and any separate volume controls.
- Recharge the affected device or replace its disposable battery if needed.
- Confirm each aid is in the correct ear and seated comfortably.
- Inspect the earpiece and wax filter for visible blockage.
- Clean accessible surfaces and replace approved parts as instructed.
Some controls change both aids together, while others adjust each side independently. Return to your prescribed starting settings if you accidentally changed them.
If the issue occurs only during streaming, compare it with normal conversation and follow your manufacturer’s connection troubleshooting. That distinction can help identify a wireless problem.
Avoid swapping hearing aids between ears as a home test. Settings and earpieces may differ by side. Don’t insert sharp objects into sound openings, force parts apart, or repeatedly increase volume to overcome muffled sound. Book an appointment at your nearest HEAR Ontario clinic if basic checks don’t resolve the difference.
What Will an Ontario Hearing Care Professional Check for Uneven Sound?
An Ontario hearing care professional will check your hearing aids and your ears separately to learn why one side sounds different. The visit typically begins with questions about the sound difference, when it occurs, recent maintenance, and whether symptoms persist without the devices. Bring both hearing aids and describe any situations that consistently trigger the problem.
A look in the ear can identify wax or other concerns that may interfere with hearing, and earwax removal may be the next step if wax is the cause. Updated hearing testing can compare each ear’s sensitivity and speech understanding with previous results. Middle ear testing, or a referral to your family physician or an ENT specialist, may be appropriate when findings suggest a medical issue. Services can vary by clinic, so ask when you book.
Device checks may include inspecting microphones, speakers, filters, tubing, and earpieces. Testing in a hearing aid test box can measure output and identify performance problems.
How Do You Keep Two Hearing Aids Performing the Same Way?
You keep two hearing aids performing the same way with a daily wipe, a check of each earpiece, and separate filter checks, even when their settings stay different. Wipe them daily with a soft, dry cloth and inspect each earpiece for buildup. Check filters individually; one may collect wax faster than the other.
Attend follow-up appointments and report recurring changes in sound or fit. Brief notes on when problems occur help us focus adjustments. The aim is dependable performance tailored to your hearing needs.
