Abstract (en)

The acoustic shock protection for acoustic devices shall be improved. In order to solve this problem there is provided a method for treating an audio signal by detecting the amplitude of the audio signal to be treated and increasing a gain applied onto the audio signal from a start level (SL) in the form of ramp over the time at most until the amplitude reaches a second amplitude value. This measure controls the sound pressure level at the loudspeaker dependent on the properties of audio signal and the energy of the audio signal is limited to a pregiven value.
