This article delves into waterproof hearing aids, examining the technology that shields them from water and discussing various levels of water resistance. Discover the advantages of incorporating this feature into your hearing aid choice, ensuring an optimal listening experience regardless of your surroundings.

What are waterproof and water-resistant hearing aids

Waterproof and water-resistant hearing aids can meet different needs for moisture and water resistance.

Waterproof hearing aids are specifically designed to withstand full immersion in water, making them suitable for activities such as swimming or showering. These models feature advanced sealing technology, specialized coatings and durable materials to prevent water from entering sensitive electronic components.

Water-resistant hearing aids are designed to handle moisture like splashes, sweat, and humidity — ideal for day-to-day use. They're often treated with protective nano-coatings or sealants to repel water and protect the delicate inner workings. However, the degree of water resistance varies by model and brand, ranging from splash-proof to fully submersible capabilities. For the best match to your lifestyle and exposure to water, a consultation with a hearing expert is recommended to assess the right level of protection for your hearing aids.

What is the difference between waterproof and water-resistant hearing aids?

Both waterproof and water-resistant hearing aids can resist water damage, but there are a few key differences. Here are the key differences between waterproof hearing aids and waterproof hearing aids.

  1. Waterproof level

Waterproof hearing aids can withstand prolonged immersion in water, while water-resistant hearing aids can resist damage from water droplets, but may not withstand heavy rain, swimming, or other water activities. The amount of time a waterproof hearing aid can withstand being submerged in water depends on the manufacturer. Some waterproof hearing aids are fine in the rain, but may not be suitable for swimming.

  1. Design and manufacturing

Manufacturing and design determine the humidity that each hearing aid can withstand. Manufacturers use different strategies to make hearing aids waterproof or water-resistant. Acoustic seal designs are popular for waterproofing because they allow sound to travel deeper into the ear canal. Waterproof devices have a valve that allows air trapped inside to escape when pressure builds up when submerged in water. Pressure mounted design prevents moisture and water ingress without valves. This design preserves sound but blocks signal transmission.

  1. Cost

Waterproof hearing aids are more expensive than water-resistant hearing aids because they protect against water damage. The internal components are expensive and sophisticated, so waterproof hearing aids cost more than hearing aids that are only water-resistant. However, for people who swim or engage in water sports, the extra cost may be worth it.

How to check the waterproof performance of hearing aids

Water resistance is a term used to describe the ability of a device or product to withstand exposure to water without damaging or impairing its functionality. So how do you check the waterproof performance of hearing aids in daily life? This requires us to understand the IP level.

What is an IP rating?

The IP (Ingress Protection) rating is a standard system used to classify and indicate the level of protection provided by electronic devices, including hearing aids, against the intrusion of solid particles such as dust and liquids such as water. The IP rating consists of two numbers.

  1. Protection against solid particles: The first number in the IP rating represents the device's level of protection against solid particles, such as dust and dirt. The range is from 0 to 6, with higher numbers indicating better protection. For example, IP rating 6 means complete dust protection, while IP rating 0 means no specific protection.
  2. Liquid ingress protection: The second number in the IP rating indicates the degree of protection the device has against the ingress of liquids, especially water. The range is from 0 to 9, with higher numbers indicating better protection. For example, IP rating 7 indicates protection against the effects of temporary immersion in water to a certain depth, while rating 9 indicates protection against high-pressure water jets.

By combining these two numbers, the IP rating provides information about a device's resistance to solid particles and liquids. For example, IP67-rated hearing aids offer complete protection from dust (6) and can withstand temporary immersion in water (7).

IP ratings are important when considering electronic devices that may be exposed to challenging environments such as water or dust. They help users determine whether a device is suitable for their specific needs and ensure that the products they choose provide adequate environmental protection.

When choosing a hearing aid, it is recommended to consider the IP rating based on your lifestyle, potential exposure to water or dust, and specific requirements. Consulting with a hearing care professional or audiologist can help find hearing aids with the appropriate IP rating that meet your needs.

Do you need hearing aids that are waterproof or water-resistant?

Whether you need waterproof hearing aids depends on things like your specific lifestyle and your wet environment. Consider the following factors to determine whether you need waterproof hearing aids:

  1. Extent of water exposure

Evaluate how often and to what extent your hearing aids are exposed to water. If you regularly wear your hearing aids for activities such as swimming, water sports, or showering, you may want waterproof hearing aids that can withstand full submersion and prolonged exposure to water.

  1. Daily Activities

Evaluate your daily activities and consider whether you encounter situations where your hearing aids may become exposed to moisture. If you live in a humid climate, sweat a lot during physical activity, or work in a high-humidity environment, waterproof hearing aids can provide adequate protection against occasional splashes and moisture.
