When one hearing aid suddenly seems quieter, sharper, or less clear than the other, it is hard to ignore. Hearing aids are designed to amplify sound in a way that feels natural, so if one sounds different, it should be examined.
At San Diego Ear, Nose & Throat Specialists in Carlsbad, audiologist Rachel Faga, Au.D., can evaluate your hearing and devices to 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.
Does Different Sound in Each Ear Mean a Hearing Aid Has Failed?
No, different sound in each ear does not automatically mean a hearing aid has failed, because each ear may have its own degree or pattern of hearing loss and need its own amount of amplification. 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 Might Muffled, Tinny, or Crackling Sound Quality Be Telling You?
Muffled, tinny, or crackling sound quality can point to wax, a fit problem, or a device fault, so the details of what you hear are useful clues. Describing the difference clearly helps narrow down the possible cause. Notice 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. Record when the problem began and which situations make it most noticeable.
In What Order Should You Test Settings When Sound Seems Uneven?
When sound seems uneven, test power and mute first, then the program and volume settings, the battery or charge, placement, and finally the wax filter, one at a time. Start in a quiet room and change only one thing before you listen again. 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. Schedule an appointment with Rachel Faga if basic checks don’t resolve the difference.
What Does a Carlsbad Audiologist Examine When One Side Sounds Weaker?
A Carlsbad audiologist examines both your ears and your hearing aids, separately, when one side sounds weaker. 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 our practice offers earwax removal when buildup is the cause. Updated hearing tests can compare each ear’s sensitivity and speech understanding with previous results. Middle ear testing or an evaluation by one of our ENT physicians 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 a repair that can’t be finished right away, we can offer a loaner in most cases.
How Can Routine Care Prevent Volume Differences Between Ears?
Routine care prevents many volume differences between ears by keeping wax, debris, and worn parts from muffling one device, even if the settings stay different. Wipe your hearing aids 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.
