Abstract
The method of adjusting the volume and the loudness in an audio device uses a volume-control unit for attenuating an audio signal by a predetermined value and a loudness-control unit for attenuating, by a further predetermined value, every component of the audio signal when in an inactive state and only the high-frequency components when in an active state. The method includes the steps of setting a volume level, associating a first and a second attenuation value with the volume level set, attenuating the audio signal by the first value and by the second value by means of the volume-control unit and the loudness-control unit, respectively, and switching the loudness-control unit selectively between the active state and the inactive state.
