Two thirds of the 250 million people worldwide who suffer from a disabling hearing impairment live in the developing world. Conventional hearing aids are much less effective in these areas because the majority of problems are due to infection damaging the ear drum and middle ear.
Hearware is a hearing aid designed for the developing world that uses bone conduction, bypassing the need for a good ear drum. The aid is even solar powered and sits on the bone behind the head sending sound vibrations through the skull to the inner ear bypassing the parts that are damaged by infection.
This device can have the colour of its casing changed to make it culturally more acceptable and dispenses with the need for hard-to-get micro batteries in places like sub-Saharan Africa.
