If you’re an active person living on Sydney’s Northern Beaches, chances are your lifestyle involves early morning ocean swims, beach walks in the spray, or workouts that leave you drenched in sweat. For hearing aid users, the question inevitably arises: can I wear my hearing aids in the water? And what does “waterproof” actually mean when it comes to these sophisticated electronic devices?
The short answer is more nuanced than most marketing materials suggest. While modern hearing aids offer impressive water resistance, truly waterproof hearing aids that can be submerged repeatedly without consequence remain rare. Understanding the difference between water-resistant and waterproof—and knowing what your devices can genuinely handle—is essential for protecting your investment and maintaining optimal hearing performance.
Understanding IP Ratings: The Truth Behind the Numbers
When manufacturers describe hearing aids as waterproof or water-resistant, they’re referring to Ingress Protection (IP) ratings—an internationally recognised standard that measures how well electronic devices resist dust and moisture. You’ll commonly see ratings like IP67 or IP68 on premium hearing aid specifications, but what do these numbers actually mean?
The IP rating system uses two digits. The first digit (ranging from 0 to 6) indicates protection against solid particles like dust. The second digit (ranging from 0 to 9) indicates the level of liquid ingress protection. For hearing aid users, that second number is what matters most.
An IP67 rating means a device can withstand immersion in up to one metre of fresh water for approximately 30 minutes under controlled laboratory conditions. IP68 offers slightly better protection—typically immersion beyond one metre, though manufacturers define the exact depth and duration. These ratings sound impressive, but there’s a critical caveat: they’re tested in fresh water at room temperature under ideal conditions.
Real-world scenarios are considerably more challenging. Salt water is corrosive and penetrates seals more aggressively than fresh water. Chlorinated pool water contains chemicals that degrade rubber seals and corrode contacts over time. Temperature extremes affect seal integrity. And the dynamic pressure changes you experience diving under a wave or swimming laps are entirely different from the static immersion used in laboratory testing.
The Practical Limits of Water Resistance
Even hearing aids with impressive IP68 ratings aren’t designed for swimming, surfing, or showering. The distinction between surviving brief water exposure and being purpose-built for aquatic use is significant. While your hearing aids might survive an unexpected splash or light rain, deliberately exposing them to water regularly will eventually compromise their internal components.
Consider what happens inside a hearing aid during water exposure. These devices contain sensitive microphones, receivers, microprocessors, and battery contacts—all housed in a case that’s measured in millimetres. Seals around battery doors, programming ports, and microphone openings can only do so much. When moisture does penetrate (and given enough exposure, it will), it can cause corrosion on circuit boards, degrade battery performance, block sound ports, and create intermittent functionality issues that are frustrating to diagnose.
For Northern Beaches swimmers and surf enthusiasts, this creates a genuine dilemma. The ocean is part of daily life, yet removing hearing aids before every beach visit means missing out on conversations, environmental awareness, and the safety benefits of being able to hear warnings or calls for help. The solution isn’t necessarily better waterproofing—it’s understanding the limitations and implementing practical strategies.
Sweat, Humidity, and Everyday Moisture Challenges
It’s not just deliberate water immersion that threatens hearing aids. Perspiration from exercise, high humidity in Sydney’s summer months, and the fine mist you encounter walking along the beach can all introduce moisture into delicate components. Sweat is particularly problematic because it contains salt and acidic compounds that accelerate corrosion even more effectively than fresh water.
Active individuals who wear hearing aids during gym sessions, tennis matches, or long beach walks need to be particularly vigilant about moisture management. The challenge is that you want to maintain hearing during these activities—communication with training partners, awareness of your surroundings, and simply enjoying music or podcasts are all important quality-of-life factors. Yet these are precisely the situations where moisture accumulation becomes problematic.
Modern hearing aids incorporate various moisture-resistance features beyond basic IP ratings. Nano-coating technologies apply a water-repellent layer at the molecular level to internal components, providing an additional barrier against moisture damage. Conformal coatings seal circuit boards. Specially designed gaskets protect vulnerable openings. These technologies significantly improve durability, but they’re defensive measures rather than guarantees of waterproof performance.
Moisture Care: Your Essential Maintenance Routine
Proper moisture management extends hearing aid lifespan and maintains performance. Whether you’ve been caught in unexpected rain, worked up a sweat during exercise, or simply worn your devices through a humid Sydney summer day, following a consistent drying routine is essential.
– Remove hearing aids before showering, swimming, or any water-based activity
– Wipe devices with a soft, dry cloth each time you remove them
– Open battery doors (or place rechargeable devices in their case) when not in use to allow airflow
– Store hearing aids in a dedicated drying container or dehumidifier overnight
– Inspect tubing and domes regularly for moisture accumulation or discolouration
– Replace wax filters and domes as recommended—blocked sound ports trap moisture
Electronic drying systems that use gentle heat or desiccant technology are particularly effective for active individuals. These purpose-built containers remove moisture more thoroughly than simply leaving hearing aids on a bedside table. For Northern Beaches residents dealing with high humidity and salt air exposure, investing in a quality drying system isn’t optional—it’s essential preventative maintenance.
If your hearing aids have been exposed to significant moisture, act quickly. Remove the batteries (or place rechargeable devices in their case), dry the exterior thoroughly, and place them in your drying system immediately. Don’t attempt to use them until they’ve had at least several hours to dry completely. Using moisture-damaged hearing aids can cause short circuits that create permanent damage.
Real-World Solutions for Water-Loving Hearing Aid Users
For those whose lifestyle genuinely revolves around aquatic activities, several practical solutions balance hearing needs with the realities of water exposure. The most straightforward approach is to have a backup plan: wear your primary hearing aids to the beach, but remove them before entering the water and store them safely in a waterproof case. This protects your investment while maintaining hearing during the social portions of your beach visits.
Some manufacturers offer specific models marketed for active lifestyles with enhanced water resistance. While these devices still shouldn’t be deliberately submerged, they tolerate sweat, humidity, and incidental moisture exposure better than standard models. If you’re particularly active or live in a coastal environment, discussing these options during your hearing aid selection process is worthwhile.
Accessory options for active lifestyles:
– Protective sleeves or covers that add an additional moisture barrier during high-risk activities
– Sport clips and retention cords that prevent devices from falling into water
– Waterproof storage cases for secure device storage at the beach or pool
– Sweatbands and headbands that reduce moisture reaching behind-the-ear devices
For serious water athletes, bone conduction headphones or specialised waterproof communication devices may complement hearing aids for specific activities. These aren’t replacements for properly fitted, programmed hearing aids, but they can fill the gap during swimming, surfing, or other water sports where traditional hearing aids simply aren’t practical.
Despite best efforts, water damage can still occur. Recognising the warning signs early allows for intervention before permanent damage develops. Intermittent sound, distortion, reduced volume, static, or devices that work initially but fail after warming up are all potential indicators of moisture problems.
If you suspect water damage, don’t delay seeking professional help. Many moisture-related issues are repairable if addressed promptly, but once corrosion starts, it progresses rapidly. Your audiologist can open the devices, professionally dry internal components, clean corroded contacts, and assess whether repairs are feasible. Waiting even a few days can transform a minor service issue into a complete device replacement.
It’s worth noting that manufacturer warranties typically exclude water damage, even on devices with high IP ratings. Insurance policies for hearing aids often cover accidental damage, including water exposure, making them a sensible investment for active individuals. Review your coverage and understand exactly what’s protected before you need to make a claim.
The Role of Professional Care and Real Ear Measurement
Moisture exposure doesn’t just risk immediate device failure—it can gradually degrade performance in subtle ways. Microphones may lose sensitivity across certain frequencies. Receivers may develop distortion. These changes might not be obvious to you, but they compromise the hearing benefit you receive.
Regular verification through Real-Ear Measurement (REM) ensures your hearing aids continue to deliver the prescribed amplification regardless of environmental conditions. REM objectively measures the sound level in your ear canal, confirming that devices meet targets across all frequencies. This is particularly important for active individuals whose hearing aids are subject to greater environmental stress than average.
At The Audiology Place, we recommend REM verification at initial fitting and periodic follow-up appointments. If your devices have been exposed to significant moisture or you’ve noticed any performance changes, verification should be part of the assessment process. This objective measurement reveals issues that subjective impressions might miss, ensuring you’re receiving optimal hearing benefit.
Making Informed Decisions About Water and Hearing Aids
Marketing for waterproof hearing aids can create unrealistic expectations. While technology has dramatically improved moisture resistance, no hearing aid on the consumer market is truly designed for regular submersion like a dive watch. Understanding this distinction empowers you to make informed decisions about when to wear your devices and when to protect them.
For Northern Beaches residents, this doesn’t mean abandoning an active coastal lifestyle—it means adapting it. Wear your hearing aids to maintain communication and awareness during beach social activities, exercise, and daily routines. Remove them before entering the water. Implement rigorous moisture management practices. Consider specialised devices for serious aquatic activities. And maintain regular professional care to catch performance degradation early.
The goal isn’t perfect waterproofing—it’s balancing optimal hearing with device longevity. By understanding what IP ratings actually mean, recognising the practical limits of water resistance, and implementing consistent moisture care routines, you can enjoy both your active lifestyle and the hearing improvement that properly maintained devices provide.
