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.
Understanding Water Resistance
Behind-the-ear (BTE) hearing aids are not typically waterproof, but many modern devices offer impressive water resistance that protects against everyday moisture exposure. Understanding this distinction is crucial for proper hearing aid care and longevity.
Water-Resistant vs. Waterproof Technology
Most contemporary BTE hearing aids are water-resistant, designed to withstand light splashes, sweat, humidity, and rain without damage. However, they cannot survive full water submersion. True waterproof hearing aids remain rare and are usually specialized devices for specific applications.
Water resistance levels are measured using IP (Ingress Protection) ratings. The two-digit system indicates protection against dust and water. Common ratings include:
IP67: Dust-tight with protection against temporary water immersion up to 1 meter for 30 minutes
IP68: Enhanced protection allowing continuous submersion beyond 1 meter for specified durations
When Water Exposure Becomes Problematic
While water-resistant BTE hearing aids handle minor moisture well, certain situations require caution:
Showering and Swimming: Remove hearing aids before water activities unless specifically designed for submersion. Water can infiltrate microphones and battery compartments, causing malfunctions.
Rain and Exercise: Most quality BTE devices withstand perspiration and light precipitation, especially those with high IP ratings. However, always dry them afterward.
Accidental Water Contact: If your device falls into water, immediate action prevents permanent damage.
Essential Protection Strategies
Proper maintenance extends your hearing aid's lifespan:
Daily Care: Use hearing aid dehumidifiers to remove accumulated moisture, particularly beneficial in humid climates. Store devices in cool, dry locations away from bathrooms.
Protective Accessories: Water-resistant covers provide additional protection for active individuals or those in moisture-prone environments.
Emergency Response: If water exposure occurs, immediately power off the device, remove batteries, and gently dry with soft cloth. Place in a dehumidifier or container with silica gel for 24 hours before reactivating.
Professional Guidance Matters
When selecting BTE hearing aids, prioritize models with appropriate IP ratings for your lifestyle. Active individuals or those in humid environments should seek devices rated IP67 or higher.
For water-based activities requiring hearing assistance, specialized waterproof hearing aids offer better solutions than standard water-resistant models.
Conclusion
While BTE hearing aids aren't fully waterproof, modern water-resistant technology provides adequate protection for daily activities. Following proper care protocols, understanding IP ratings, and consulting a Hear Expert ensures optimal device performance and longevity. When in doubt, removing hearing aids before water exposure remains the safest approach for protecting your investment in better hearing.
