    Abstract: A programmable intraductal hearing aid includes a microphone, a dynamically programmable filter means, an adjustable power amplifier, and a sound reproduction transducer, powered by a battery. The filter having controlled capacitors is made, together with a programming memory and its interface, in the form of at least one integrated circuit including at least one oscillator associated with at least one d.c. voltage step-up transformer for energizing the memories, the whole set being powered by a miniature low voltage battery. A power amplifier, powered by the same battery is made in a single integrated circuit provided with external decoupling capacitors.
