How Do You Maintain a BTE Hearing Aid?

 Behind-the-Ear (BTE) hearing aids are one of the most popular and versatile types of hearing aids, offering powerful amplification and advanced features. However, to ensure their longevity and optimal performance, regular maintenance is essential. Proper care can prevent malfunctions, extend battery life, and improve sound quality.

In this article, we’ll cover everything you need to know about maintaining a BTE hearing aid, including daily cleaning, battery care, troubleshooting common issues, and when to seek professional servicing.

Understanding the Components of a BTE Hearing Aid

Before diving into maintenance tips, it’s important to understand the main components of a BTE hearing aid:

  • Microphone: Captures sound from the environment.

  • Amplifier: Processes and amplifies the sound.

  • Receiver (Speaker): Delivers the amplified sound into the ear.

  • Ear Hook & Tubing: Connects the main device to the earmold or dome inside the ear.

  • Earmold or Dome: Custom-fit or standard part that sits in the ear canal.

  • Battery Compartment or Rechargeable Battery: Powers the hearing aid.

Each of these components requires specific maintenance to ensure the device functions correctly.

Daily Maintenance Tips

1. Clean the Hearing Aid Regularly

Dirt, sweat, and earwax can accumulate on your hearing aid, affecting its performance. Here’s how to clean it:

  • Wipe the exterior with a dry, soft cloth or a hearing aid cleaning wipe every night.

  • Check the microphone ports and gently brush away any debris with a soft-bristled brush.

  • Inspect the earmold or dome for wax buildup and clean it using a wax loop or specialized cleaning tool.

  • Ensure the tubing is clear by detaching it from the hearing aid and using an air blower or cleaning tool to remove moisture and debris.

2. Keep the Hearing Aid Dry

Moisture is one of the biggest threats to a hearing aid’s functionality. Follow these steps to protect your device:

  • Remove the hearing aid before showering, swimming, or using hair products.

  • Store it in a dry, cool place when not in use.

  • Use a dehumidifier or drying kit overnight to remove moisture buildup.

3. Handle the Battery with Care

  • Open the battery compartment at night to prevent moisture buildup and extend battery life.

  • Remove dead batteries promptly to avoid corrosion.

  • Store spare batteries in a cool, dry place away from metal objects to prevent short circuits.

  • For rechargeable BTE hearing aids, follow the manufacturer’s charging guidelines and avoid overcharging.

Weekly and Monthly Maintenance

1. Deep Clean the Earmold and Tubing

For BTE hearing aids with custom earmolds, wax and moisture can accumulate over time.

  • Detach the earmold and tubing from the hearing aid and soak them in warm, soapy water once a week.

  • Rinse thoroughly and let them dry completely before reattaching.

  • If using domes instead of earmolds, replace them periodically as per the manufacturer’s recommendation.

2. Check for Sound Blockages

  • If your hearing aid’s volume seems lower than usual, inspect the sound outlet for wax or debris.

  • Clean or replace the wax filter if necessary.

3. Inspect for Wear and Tear

  • Check the tubing for cracks, stiffness, or discoloration—replace if needed.

  • Ensure the ear hook is securely attached and in good condition.

  • Examine the battery contacts for corrosion and clean them with a dry cotton swab if necessary.

Troubleshooting Common Issues

Even with proper care, BTE hearing aids may sometimes experience issues. Here’s how to troubleshoot common problems:

1. No Sound or Weak Sound

  • Ensure the hearing aid is turned on and the battery is properly inserted.

  • Replace the battery if it is dead.

  • Check for wax buildup in the earmold or tubing and clean as needed.

  • Ensure the tubing is not clogged or twisted.

2. Whistling or Feedback Noise

  • Ensure the earmold or dome fits snugly in the ear canal.

  • Clean any wax buildup that might be causing sound leakage.

  • Reduce the volume slightly to see if the feedback stops.

3. Intermittent or Distorted Sound

  • Check for moisture buildup in the tubing or earmold—dry it with an air blower or place it in a drying kit.

  • Inspect the microphone and speaker ports for debris and clean them gently.

  • If using rechargeable batteries, make sure they are holding a charge properly.

When to Seek Professional Servicing

While regular maintenance can prevent many issues, some problems require professional attention. Contact your audiologist or hearing aid provider if:

  • The hearing aid is still not functioning after troubleshooting.

  • You notice persistent distortion or static sounds.

  • The tubing or earmold is damaged and needs replacement.

  • The device has been exposed to excessive moisture or physical damage.

  • You need adjustments in programming or fitting.

Additional Tips for Long-Term Hearing Aid Care

  • Store the hearing aid in a protective case when not in use.

  • Avoid exposing it to extreme temperatures, such as direct sunlight or freezing conditions.

  • Schedule regular checkups with an audiologist for professional cleanings and performance evaluations.

Conclusion

Maintaining a BTE hearing aid requires consistent cleaning, careful handling, and routine inspections to ensure optimal performance. By following these maintenance tips, you can extend the lifespan of your device, improve sound quality, and reduce the likelihood of repairs. If you experience persistent issues, consulting a professional will ensure your hearing aid continues to function at its best.
