ABSTRACT:
A hearing aid to be worn by an individual of impaired hearing ability producing analog output signals of improved intelligibility. The hearing aid includes a wearable, programmable digital signal processor for processing digital samples of the analog signals coupled thereto in real time and providing analog output signals having the processed characteristics. The hearing aid program stored in the signal processor is continuously executed and modifies the analog signals coupled thereto by digital filtering in real time in accordance with the varying noise levels contained in the received audible signals. The modification of the signals includes noise supression.
