Abstract
A hearing aid has an input transistor, an amplifier and transmission circuit, an output transducer and a calculating unit that realizes fuzzy logic functions. The calculating unit responds to a tap signal taken at the amplifier and transmission circuit and supplies 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, operates reliably and enables an optimum matching to the specific requirements of the hearing aid user.
