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.

13. A hearing aid, comprising:
-
a sound receiver that receives sound waves and generates a microphone signal based on the sound waves;
a transmitting unit that receives the microphone signal and generates a power signal based on the microphone signal;
a sound generator that receives the power signal and generates a sound based on the power signal;
a memory that stores a generation parameter;
a tone signal generator connected to the memory that generates a tone signal as a function of a trigger signal and the generation parameter; and
an audio signal unit functionally linked to the sound generator that generates the trigger signal and sends the tone signal to the sound generator. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
