Abstract
A hearing aid has an input transducer, an amplifier and transmission circuit, an output transducer and a calculating unit working according to the principle of a neural structure. The calculating unit responds to a tap signal taken at the amplifier and transmission circuit and units an event signal that is supplied to the amplifier and transmission circuit and influences an output signal emitted thereby. At least the calculating unit is implemented in digital circuit technology. Such a hearing aid can be manufactured with little development and circuit outlay, works reliably and enables an optimum matching to the specific requirements of the hearing aid user.
