Abstract :
A programmable microprocessor-controlled analog hearing aid that automatically maintains amplified signals at the same sound-pressure level and spectrum at a given patient´s eardrum is under development. The unique feature of the hearing aid is the placement of a feedback microphone near the eardrum to form a closed-loop servo. This system is designed to compensate for the effects of signal variations in the environment. The hardware and software are described
