People who suffer from hearing loss typically have to deal with going without their hearing aids when they are swimming or at the beach, or in the elements. This is one of the reasons why Siemens developed the Aquaris waterproof hearing aid, which will allow users to take them anywhere.
The Aquaris hearing aid offers watertight seals and membranes to keep moisture out while still allowing the flow of air, which is necessary when using zinc air batteries. They can be submerged for up to 30 minutes without any damage, and also incorporate a Bluetooth transmitter and a microphone, allowing them to double as a hands-free system.
This system allows people to communicate with hearing-impaired athletes in the water, something which was problematic before. The Aquaris hearing aid sells for about $2500(USD).
