ABSTRACT:
A method for reproducing audio signals of at least two different sources, a first volume for reproducing audio signals of a first source being able to be preselected, in which, during simultaneous reproduction of the audio signals of the first and the at least second source, the reproduction of the audio signals of the at least second source occurs at a volume that is raised compared to the first volume at least by a differential volume. This allows for a comprehensible reproduction of prioritized audio signals of the second source even against the background of a continuous reproduction of audio signals of a first source.
