Saad Bhamla and Soham Sinha, from Georgia Tech, were able to design and create a 3D-printed hearing aid that costs under one dollar. The device takes design inspiration from hearing aid models that were created in the 1950s, and it is a device that rests on the user's body and has attachable earphones.
Bhamla and Sinha developed the pair to be used for individuals who experience age-related hearing loss. However, the new design could be a cost-effective hearing loss solution for individuals who may not have the resources to access conventional hearing aids.
The 3D-printed hearing aid currently does not meet the standards of the World Health Organization, however, Bhamla and Sinha are working to reduce the noise in the internal circuitry to meet these standards.
