Waterproof vs. Water-Resistant Hearing Aids: What You Need to Know

Hearing aids are sophisticated micro-electronic devices that are highly sensitive to moisture, sweat, and environmental liquids. At Cadenza Hearing, we understand that durability is a top priority for users and distributors alike. This guide explores the latest in moisture-protection technology and the reality of "waterproof" hearing aids.

1. Is There Such a Thing as a Truly Waterproof Hearing Aid?

A common question in the audiology market is: "Can I swim in my hearing aids?"

Technically, while most modern devices are water-resistant, very few are 100% waterproof for high-impact aquatic activities.

• Water-Resistant: The device can withstand minor exposure, such as light rain or perspiration, for a short duration.
• Waterproof: The device can be fully submerged without damage.

While industry advancements have made devices incredibly resilient, long-term exposure to high humidity or chemically treated pool water can still affect delicate internal components. For maximum longevity, we recommend using a dehumidifier to maintain your investment.

2. The Latest Technology in Moisture Protection

In the last decade, hearing aid manufacturing has evolved significantly. Top-tier manufacturers like Austar/Cadenza utilize two primary layers of defense:

• Structural Barriers: Redesigned casings with tighter seals and protective membranes between compartments.
• Nano-Coating Technology: A specialized water- and oil-resistant nano-layer applied to both internal circuits and external housings, repelling liquid on a molecular level.

3. Do You Need Water-Resistant Hearing Aids?

Choosing an IP68-rated device is essential if you fit any of the following profiles:

• Active Lifestyles: You enjoy kayaking, sailing, or hiking in unpredictable weather.
• Humid Climates: You live in tropical or coastal regions with high atmospheric moisture.
• Heavy Perspiration: You wear your devices during strenuous exercise or suffer from hyperhidrosis.
• Accident Prevention: You want peace of mind against dropping devices in water or accidentally wearing them in the shower.

4. Understanding IPX Ratings: What is IP68?

Before purchasing or sourcing hearing aids, it is crucial to check the Ingress Protection (IP) rating, as defined by the International Electrotechnical Commission (IEC).

The rating consists of two digits (e.g., IP68):

• First Digit (0–6): Protection against solid particles like dust.
• Second Digit (0–9): Protection against liquids.

The Liquid Protection Scale:

For instance, the AUSTAR FUGUE X series and most of Cadenza’s BTE and RIC hearing aids carry an IP68 rating—the highest standard for dust and water resistance in the industry.

5. Expert Care Tips for Longevity

Even with an IP68 rating, professional care extends the life of the device:

• Wipe Down: After heavy sweating or rain exposure, dry the exterior with a soft, lint-free cloth.
• Open Battery Doors: If your model uses zinc-air batteries, open the compartment at night to allow air circulation.
• Avoid Saltwater: Salt is corrosive. If exposed to ocean water, consult your manual for cleaning instructions immediately.
