Gabe and Peter have two hearing impaired friends who struggle even with hearing aids due to too much ambient sound. Gabe and Peter have designed a new directional hearing aid with a two-directional array of 8 to 18 microphones spaced appropriately to amplify the sounds of all voice frequencies coming from directly in front of the wearer. The sound signals are then digitally processed in a custom chip to diminish the sounds from other directions. The amplified output is then connected to a conventional hearing aid transducer. This new technology is inexpensive and can be built into personal accessories such as hats and briefcases.
