Ear Wax and Hearing Aids

For individuals who rely on hearing aids, managing ear wax is not just a matter of comfort—it is a critical component of maintaining the performance and longevity of their devices. Hearing aids and ear wax have a complex relationship; the devices can contribute to wax build-up, and the wax, in turn, can wreak havoc on the sensitive electronics of the hearing aids. Understanding this relationship is the first step toward developing a proactive ear care routine that protects both your hearing and your investment.

How Hearing Aids Contribute to Wax Build-Up

Hearing aids, particularly in-the-ear (ITE) or in-the-canal (ITC) styles, act as a plug in the ear canal. This physical blockage can interfere with the ear’s natural self-cleaning mechanism. The skin inside your ear canal is like a slow-moving conveyor belt, designed to carry wax and dead skin cells from the inside of the ear to the outside. A hearing aid can act as a dam, preventing this natural migration.

Furthermore, the presence of a hearing aid can stimulate the ceruminous glands to produce more wax. The ear may interpret the hearing aid as a foreign object that it needs to protect against, leading to an increase in wax production. This creates a cycle where the hearing aid causes more wax, and the wax then causes problems for the hearing aid.

The Damaging Effects of Wax on Hearing Aids

Ear wax is the number one enemy of hearing aids. It is responsible for a significant percentage of all hearing aid repairs. The combination of wax, moisture, and debris can damage the delicate electronic components in several ways.

•Blocked Sound Port: The most common issue is a blockage of the sound port or receiver. Even a tiny amount of wax can plug the small opening where the sound comes out, resulting in weak, distorted, or no sound at all.

•Clogged Vents: Many hearing aids have small vents designed to allow for air circulation and to prevent a “plugged up” feeling. Wax can clog these vents, affecting sound quality and comfort.

•Damage to Internal Components: If wax works its way inside the hearing aid, it can damage the sensitive internal electronics, including the receiver and microphone. This type of damage often requires professional repair.

Symptoms of a Wax-Related Hearing Aid Problem

How can you tell if ear wax is affecting your hearing aid? Look for these signs:

•The hearing aid seems weak or dead, even with a fresh battery.

•You hear distorted or unclear sound.

•The hearing aid produces feedback or a whistling sound. This can happen when the sound that is supposed to go into your ear is blocked by wax and is instead reflected back into the hearing aid’s microphone.

•You can see visible wax on the hearing aid, particularly on the sound port.

A Proactive Approach: Cleaning and Maintenance

To protect your hearing aids, a daily cleaning routine is not just recommended—it is necessary.

Daily Cleaning:

1.Wipe Down the Hearing Aid: Use a soft, dry cloth to wipe the entire surface of your hearing aid.

2.Use a Wax Pick and Brush: Most hearing aids come with a small tool kit that includes a wax pick and a brush. Use these to gently remove any visible wax from the openings of the hearing aid.

3.Check the Wax Guard: Many hearing aids have a small, white filter called a wax guard that protects the receiver. If this guard is clogged, it needs to be replaced. Follow the manufacturer’s instructions for changing the wax guard.

Regular Professional Cleanings:

In addition to your daily routine, it is a good practice to have your hearing aids professionally cleaned and checked by your audiologist on a regular basis. They have specialised tools to provide a deeper clean than you can at home.

The Importance of Professional Ear Cleaning

For hearing aid users, regular professional ear cleaning is just as important as cleaning the devices themselves. Because you are more prone to wax build-up, having your ears checked and cleaned by a professional every 6 to 12 months is a wise investment.

Microsuction is the ideal method for hearing aid users. It is a dry procedure, which means there is no risk of introducing moisture into the ear that could later damage the hearing aid. It provides a clear view of the ear canal, ensuring that all wax is removed and that the ear is in a healthy condition to accommodate the hearing aid.

By taking a two-pronged approach—meticulous daily cleaning of your hearing aids and regular professional cleaning of your ears—you can ensure that your devices work effectively and that you continue to hear the world around you with clarity.
