Abstract
A hearing aid having a microphone for conversion of sound into an input audiosignal, a signal processor for processing the input audiosignal, a receiver for conversion of the processed signal into sound, an audio amplifier for supplying current to the receiver in response to the processed signal, a battery for current supply of the signal processor, the audio amplifier, and the receiver, and a current limiter connected in series between the battery and the audio amplifier for analogue limitation of the current supplied by the battery to the audio amplifier in response to the battery output voltage.
