Design of a digital hearing aid

This design project has a lot of future potential and follow on work ahead. As improvements are made in the miniaturization of circuitry, the concept of a programmable digitized hearing aid grows more feasible. The one that was built and tested as a part of this project had several shortcomings that were related to using non-specialized components. To be useful to the consumer, it needs to be repackaged into a smaller, more efficient case. The power consumption needs to be minimized over the current power requirements. This would probably involve designing and building an ASIC that would be specifically tailored for usage in a hearing aid. A user friendly PC based interface program needs to be written to allow easier updates to the hearing profile tables that are stored in non-violative memory.
