Waterproof hearing aid

    A waterproof hearing aid could allow the hearing impaired to take part in more activities while still enjoying the added accessibility that hearing aids provide.
    The rugged hearing aid will be dustproof, shockproof and waterproof at depths up to 3 feet for as long as 30 minutes. The battery compartment will be connected using a silicon sealant, and oxygen will be able to reach the zinc air batteries by moving through a waterproof membrane.
