Hearing aids rarely fail all at once. Usually, they just fade. A voice across the dinner table sounds a little flatter, the television creeps up a few notches, and a faint whistle starts every time you pull on a winter hat. Many people assume their hearing has worsened or the device is wearing out. Often, neither is true.
Hearing loss is far more common than most Canadians realize. When the Canadian Health Measures Survey tested hearing directly, it found that four in ten adults aged 20 to 79 had at least slight hearing loss in one or both ears. For anyone who relies on hearing aids, it pays to know why they falter.
The Two Culprits Behind Most Repairs
For electronics, the ear canal is a hostile place: warm, humid, and constantly producing wax. According to hearing aid manufacturer Signia, roughly 60–70% of hearing aids sent in for repair are simply clogged with earwax or degraded by other organic material. Wax blocks the tiny sound outlet and its protective wax guard, muffling the sound or silencing it completely. Wax in the ear canal can also bounce sound back toward the microphone, causing the whistling many wearers mistake for a technical fault.
The relationship works both ways. A hearing aid sits exactly where earwax would normally make its way out, and clinical reviews note that impacted earwax affects more than 30% of older adults and is often seen in hearing aid wearers. Sometimes the problem isn’t in the device at all. It’s in the ear.
Moisture is the second culprit. Sweat, humid summers, and even Canadian winters take a toll: stepping from freezing air into a warm room causes condensation on cold electronics. Over time, moisture corrodes battery contacts and circuitry, leading to crackling, sound that cuts in and out, and batteries that drain too quickly.
What You Can Safely Do at Home
A few minutes of daily care prevents most of these problems:
- Wipe the devices every night with a soft, dry cloth. Avoid water, alcohol, and household cleaners.
- Brush the microphone ports and sound outlet, holding the device facing downward so debris falls out rather than in.
- Change wax guards and domes regularly, before the sound is completely blocked.
- Dry them overnight in a drying case, especially after exercise or a humid day.
- Put your aids in last, after hairspray, sunscreen, and a steamy shower.
Never open the casing, which can void the warranty, or dry a damp aid with a hair dryer or microwave. Skip cotton swabs, too; they push wax deeper.
When Home Care Isn’t Enough
Daily cleaning only reaches the surface. A professional cleaning clears the internal sound channels with specialized equipment and lets a clinician check the device’s output against your prescription.
Book a check if static continues after cleaning, whistling persists when the fit feels right, sound cuts in and out, batteries drain unusually fast, or the casing is cracked. Many of these faults can be fixed in a single visit. Deeper problems, such as a failed receiver, usually go back to the manufacturer and are often covered under warranty. Before shopping for new devices, it’s worth exploring the full range of hearing aid cleaning and repair options available to you.
Why Maintenance Pays Off
Public funding only goes so far. In Ontario, the Assistive Devices Program covers 75% of the cost of hearing aids, up to $500 per side. It funds replacements only when the equipment is worn out, out of warranty, and can’t be repaired at a reasonable cost, and it won’t pay to repair damage caused by misuse or neglect. Looking after your aids protects what you’ve paid for.
There’s a human cost, too. A hearing aid that crackles tends to end up in a drawer, and untreated hearing loss has been linked to social isolation, depression, and a poorer quality of life, especially in older adults.
The fix is usually simple: a nightly wipe, a fresh filter, a drying case, and a professional check every few months. More often than not, a hearing aid that seems “dead” is really just waiting to be cleaned.
Why Regular Hearing Aid Care Matters
Hearing aids are designed to make everyday communication easier, but they need regular care to perform at their best. When sound becomes weak, distorted, or inconsistent, the problem is not always a failing device. Earwax, moisture, blocked filters, and everyday buildup are often responsible and can usually be prevented with simple maintenance. Just as Nutrition Advice TheWeeklyHealthiness can help people make informed choices about their overall wellness, proper hearing-aid care can help protect hearing support and maintain a better quality of life.

A few minutes of cleaning each day, proper drying, and timely replacement of wax guards can help extend the life of your hearing aids and keep them working reliably. If problems continue despite regular care, professional cleaning and inspection can identify issues that are difficult to fix at home.
Taking care of your hearing aids is also an investment in your quality of life. Instead of putting a troublesome device away, address the problem early. With consistent maintenance and professional support when needed, your hearing aids can continue helping you stay connected to the people and conversations that matter most.
