Are BTE Hearing Aids Waterproof?

 Behind-the-Ear (BTE) hearing aids are among the most durable and versatile types of hearing aids available today. Given their external placement behind the ear, users often wonder whether BTE hearing aids are waterproof. While some models are designed to withstand moisture, it is important to understand the limitations of water resistance in hearing aids.

Are BTE Hearing Aids Truly Waterproof?

The short answer is no, most BTE hearing aids are not completely waterproof. However, many modern hearing aids are water-resistant, meaning they can withstand exposure to moisture but not full submersion in water. True waterproof hearing aids are rare and typically designed for specialized use cases.

Waterproof vs. Water-Resistant BTE Hearing Aids

1. Waterproof Hearing Aids

  • These hearing aids are fully sealed and can be submerged in water without damage.

  • Very few hearing aids are truly waterproof, as prolonged exposure to water can affect delicate electronic components.

  • Some hearing aids marketed as “waterproof” may still have limitations on how long they can be submerged.

2. Water-Resistant Hearing Aids

  • Most modern BTE hearing aids fall into this category.

  • They can handle light splashes, sweat, humidity, and rain, but they should not be submerged in water.

  • Water resistance is rated using the IP (Ingress Protection) rating system, which indicates the level of protection against dust and water.

Understanding IP Ratings for BTE Hearing Aids

IP ratings consist of two numbers, such as IP67 or IP68:

  • The first digit (0-6) represents dust protection.

  • The second digit (0-9) represents water resistance.

Here’s what some common IP ratings mean for BTE hearing aids:

  • IP67: Dust-tight and protected against temporary immersion in water (up to 30 minutes at 1 meter depth).

  • IP68: Dust-tight and capable of withstanding continuous immersion in water (deeper than 1 meter for a specified duration).

Most high-quality BTE hearing aids have an IP67 or IP68 rating, making them resistant to accidental water exposure but not fully waterproof.

Can You Wear BTE Hearing Aids in Water?

While water-resistant BTE hearing aids can handle occasional moisture, they are not designed for prolonged exposure to water. Here are some common situations and how BTE hearing aids react to them:

1. Showering

  • Not recommended unless the hearing aid is specifically labeled as waterproof.

  • Water can seep into the microphone or battery compartment, leading to malfunction.

2. Swimming

  • Most BTE hearing aids should not be worn while swimming.

  • If you need hearing assistance in water, consider special waterproof hearing aids or hearing protection devices.

3. Rain and Sweat

  • Many modern BTE hearing aids are built to withstand rain and sweat, especially if they have a high IP rating.

  • However, it’s still advisable to wipe them dry after exposure to moisture.

4. Accidental Drops in Water

  • If your BTE hearing aid accidentally falls into water, remove it immediately, dry it thoroughly, and use a hearing aid dehumidifier.

How to Protect Your BTE Hearing Aids from Water Damage

To extend the lifespan of your hearing aids and prevent water-related issues, follow these best practices:

1. Use a Hearing Aid Dehumidifier

  • A hearing aid dehumidifier or drying box can remove excess moisture and keep your device functioning properly.

  • It’s especially useful for individuals living in humid climates.

2. Store Your Hearing Aids Properly

  • Keep your hearing aids in a dry, cool place when not in use.

  • Avoid storing them in bathrooms or other humid environments.

3. Use a Water-Resistant Cover

  • Some manufacturers offer water-resistant sleeves or covers to add extra protection.

  • These can be useful for individuals who sweat a lot or engage in outdoor activities.

4. Check Your Hearing Aid’s IP Rating

  • Before purchasing a hearing aid, ask about its IP rating to understand its level of water resistance.

  • If you need a hearing aid that can handle moisture, choose a model with at least an IP67 rating.

5. Avoid Water Exposure When Possible

  • Always remove your hearing aids before swimming, showering, or engaging in water sports.

  • If you forget and your hearing aid gets wet, dry it immediately.

What to Do If Your BTE Hearing Aid Gets Wet

If your hearing aid is accidentally exposed to water, follow these steps:

  1. Turn it off and remove the battery (if applicable).

  2. Wipe it dry with a soft, clean cloth.

  3. Place it in a hearing aid dehumidifier or a drying container with silica gel.

  4. Avoid using a hairdryer or other heat sources, as excessive heat can damage internal components.

  5. Wait at least 24 hours before turning it back on.

  6. If the hearing aid doesn’t work, consult your audiologist or manufacturer for further assistance.

Conclusion

While most BTE hearing aids are not fully waterproof, many are water-resistant, allowing them to handle minor moisture exposure.To extend the life of your BTE hearing aid, avoid water exposure, use a dehumidifier, and store it properly.For individuals who need hearing aids for water-based activities, specialized waterproof hearing aids may be a better option. Consulting a Hear Expert or audiologist can help you choose the best hearing aid for your lifestyle and needs, ensuring you receive professional guidance from experienced hearing care specialists.
