If one hearing aid suddenly seems quieter, sharper, or fuzzier than its partner, it’s natural to wonder whether something is wrong. Hearing aids are designed to amplify sound in a way that feels natural, so a noticeable difference between them should be examined.

At Lambton Audiology Associates, audiologists Kimberly A. Eskritt, M.Cl.Sc, Au.D., Reg. CASLPO, and Katelyne B. Lebert, M.Cl.Sc., evaluate hearing and devices for patients across Lambton County from our offices in Sarnia and Petrolia. They can determine whether the difference comes from maintenance needs, programming, fit, or a change in your ears. Most patients can start troubleshooting at home, then seek professional care if the difference persists.

Should Each Hearing Aid Sound Exactly Like Its Partner?

Each hearing aid doesn’t always need to sound exactly like its partner, 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 Uneven Hearing Aid Sound Changes Are Worth Noting?

Uneven hearing aid sound changes worth noting include one side seeming louder or softer, speech sounding muffled or distorted in one ear, whistling or crackling, and sound cutting 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. Common experiences include:

• 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. Jot down when the problem began and which situations make it most noticeable.

How Can You Narrow Down the Cause Before Your Appointment?

You can narrow down the cause before your appointment by checking each hearing aid’s power, program, volume, battery or charge, fit, and wax filter, one step at a time. Start in a quiet room and avoid changing several things at once. 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 a visit with Kimberly Eskritt or Katelyne Lebert if basic checks don’t resolve the difference.

What Happens at an Uneven Sound Appointment in Sarnia or Petrolia?

At an uneven sound appointment in Sarnia or Petrolia, your audiologist evaluates the hearing aids and your ears separately to find what is causing the difference. 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.

An ear examination can identify wax or other concerns that may interfere with hearing, and ear wax management may be the next step. Updated hearing testing can compare each ear’s sensitivity and speech understanding with previous results. Middle ear testing or referral to one of the local ENT physicians we work with may be appropriate when findings suggest a medical issue.

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. If a device needs repair, ask about a loaner hearing aid while yours is away.

How Do You Keep One Hearing Aid From Drifting Out of Step?

You keep one hearing aid from drifting out of step with daily cleaning, separate filter checks, and regular follow-up visits, even if the two devices keep different settings. 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.

Have Both Hearing Aids Checked at Lambton Audiology Associates

An uneven pair doesn’t have to stay that way. Kimberly Eskritt and Katelyne Lebert can determine whether the next step is maintenance, adjustments, repair, or further hearing assessment. Bring both hearing aids, your charger (if charging is a concern), and notes on when the difference occurs.

Call or text our Sarnia office at 226-210-4283 or our Petrolia office at 226-210-4316, or send a message to Lambton Audiology Associates to book a hearing aid evaluation.
