Abstract
The invention relates to a hearing aid having a sound receiver and a sound generator. The hearing aid also has an audio signal unit that is functionally linked to the sound generator and has a tone signal generator for generating a tone signal as a function of a trigger signal and of a generation parameter which represents a frequency that can be perceived by a human ear. The hearing aid also has a memory, connected to the tone signal generator, for storing the generation parameter. The audio signal unit changes the generation parameter stored in the memory, generates a trigger signal for each tone signal requiring to be generated, sends said trigger signal to the tone signal generator, and sends the generated tone signal to the sound generator.
