Understanding Your Hearing Aid Components

Hearing aids are complex devices made up of several key parts, each playing an important role in how well they work. Understanding what makes up your hearing aid helps you clean and maintain each component correctly. The microphone picks up sound from your environment and converts it into electrical signals. The amplifier increases the volume of these signals based on your specific hearing loss pattern. The receiver, sometimes called a speaker, delivers the amplified sound into your ear canal. The battery powers the entire device, and modern hearing aids typically use zinc-air batteries in sizes ranging from 10 to 675, with size 312 being one of the most common.

The casing or shell of your hearing aid is usually made from plastic or acrylic material designed to be durable yet lightweight. Behind-the-ear (BTE) models have a curved piece that sits over the top of your ear, while receiver-in-the-ear (RIE) models have the receiver positioned in the ear canal itself. In-the-ear (ITE) models sit entirely within your ear canal or ear bowl. Each style has different components exposed to earwax, moisture, and debris, which affects how you should clean them. The tubing that connects BTE hearing aids to the earmold can accumulate wax buildup over time and may need replacement every 6 to 12 months depending on how much wax your ears produce.

Many hearing aids now include wireless technology that connects to phones, televisions, and other devices through Bluetooth or proprietary wireless systems. These components require batteries that drain faster than traditional hearing aids. Some newer models are rechargeable, using lithium-ion batteries that you charge overnight using a specialized charging case. Understanding whether your hearing aid uses disposable or rechargeable batteries affects your daily maintenance routine. According to the National Institute on Deafness and Other Communication Disorders, approximately 37.5 million Americans report some degree of hearing loss, and proper maintenance extends the life of these devices significantly.

Practical takeaway: Identify which type of hearing aid you have and locate each component. Check your hearing aid manual or ask your audiologist which parts are removable and which are sealed. This knowledge prevents damage during cleaning.

Daily Cleaning Procedures and Best Practices

Daily cleaning is the foundation of hearing aid maintenance and takes only a few minutes each morning or evening. Start by using a soft, dry cloth to wipe down the exterior of your hearing aid. Microfiber cloths work best because they do not leave lint and gently remove surface moisture and earwax. Never use a cloth that is wet or damp, as moisture is the primary enemy of hearing aid electronics. Wipe the entire outer surface, paying special attention to crevices and the area where the earmold connects to the hearing aid body, as earwax tends to accumulate there.

For behind-the-ear models with earmolds, the earmold itself needs separate attention from the hearing aid body. Hold the earmold under lukewarm running water and gently rub it with your fingers to remove surface earwax and debris. Some people use a small soft brush designed for hearing aid care to gently clean the earmold surface. Never submerge the hearing aid body itself in water unless your specific model is marked as waterproof, and even then, follow manufacturer instructions carefully. Dry the earmold completely with a soft cloth before reconnecting it to the hearing aid.

Earwax buildup is one of the most common issues affecting hearing aid performance. According to audiology research, approximately 20 to 50 percent of older adults produce excessive earwax. If you fall into this category, you may need to clean your hearing aid more frequently than the standard daily schedule. Some people with high earwax production find that cleaning twice daily helps maintain optimal sound quality. If you notice reduced sound output or feedback (whistling sounds), earwax accumulation is often the culprit. Inspect the speaker opening or receiver port for visible wax and gently remove it with the small brush or wax pick that came with your hearing aid kit.

The battery compartment should be opened daily and left open overnight to allow any accumulated moisture to evaporate. This simple step extends battery life and prevents corrosion inside the compartment. If you notice white or blue powder inside the battery compartment, that indicates corrosion. Clean it gently with a dry cloth, and if the corrosion is heavy, your audiologist can help remove it without damaging the device. Replace the battery only with the exact size your hearing aid requires, and note the expiration date on the battery package to ensure freshness.

Practical takeaway: Set a daily cleaning routine at a consistent time, such as before bed. Gather your supplies (soft cloth, small brush, wax pick) in one place so cleaning takes less than two minutes. Keep a small container nearby to store the items you remove, such as old batteries or debris.

Managing Moisture and Humidity Challenges

Moisture is the leading cause of hearing aid malfunction, accounting for roughly 50 percent of all hearing aid repairs. Your hearing aids are exposed to moisture from multiple sources: earwax, ear canal fluid, sweat, humidity in the air, and direct water exposure from showers or rain. Even though modern hearing aids have some water-resistant coatings, the internal electronics are not waterproof unless specifically designated. Managing moisture requires both prevention and active drying techniques implemented into your daily routine.

Sweat poses a particular challenge for people who exercise, live in humid climates, or spend time outdoors in warm weather. Sweat can seep into the microphone ports and receiver openings, causing internal corrosion that damages the circuit board. If you exercise regularly or engage in activities that cause sweating, wipe your hearing aids with a dry cloth immediately after the activity finishes. Some people use a thin headband or sweatband to keep moisture away from their hearing aids during exercise. If you participate in sports or activities where water exposure is likely, discuss waterproof or water-resistant models with your audiologist, as these are designed to withstand moisture better than standard models.

A hearing aid drying container or dehumidifier is an essential tool for any hearing aid wearer. These containers use desiccant material (usually silica gel) to absorb moisture from your hearing aids overnight. The desiccant material changes color when saturated, typically turning from blue or orange to pink or colorless, indicating when it needs replacement. Some drying containers use electric heating to speed up the drying process. Simply place your open hearing aids and opened battery compartments in the container each night. This routine removes accumulated moisture and helps prevent internal corrosion. Replace desiccant packs approximately every 1 to 3 months depending on humidity levels in your area and how much moisture your ears produce.

If your hearing aids get wet from a shower, rain, or accidental submersion, do not panic, but act quickly. Remove the battery immediately to stop any electrical current. Open the battery compartment and remove any visible moisture with a soft cloth. Place the hearing aids and the open battery compartment in your drying container for at least 24 hours, preferably 48 hours. Do not attempt to use them until this drying period is complete. Some people keep a backup pair of hearing aids during the drying period to maintain communication. For severe water damage, contact your audiologist, as they have professional drying equipment that may restore the devices.

Practical takeaway: Purchase a hearing aid drying container and use it every night without exception. Check your desiccant material weekly and note when replacement is needed. Keep extra desiccant packs on hand so you never run out.

Replacing Tubing, Domes, and Wax Guards

Several hearing aid components wear out with regular use and require periodic replacement. Earmold tubing on behind-the-ear models becomes stiff, discolored, and cracked over time due to exposure to earwax, oils from your skin, and fluctuations in temperature and humidity. Hard tubing typically needs replacement every 6 to 12 months, depending on how much earwax your ears produce and how often you clean the tubing. Soft tubing may need replacement more frequently, sometimes every 3 to 6 months. When tubing becomes discolored or cracked, sound quality diminishes and moisture can enter the hearing aid body through the damaged tubing. Replacement tubing is inexpensive compared to hearing aid repair costs and is well worth the investment.
