ABSTRACT:
A radio receiver having switching-over to traffic announcement wherein the bass and treble frequency responses and the volume are changed to a value which is subjectively optimum for the respective actual driver and the announcement becomes more pleasant and easier to understand for him/her without the necessity for the driver to manually change the bass and treble controls. The switching-over of the bass and treble audio frequencies preferably occurs a short time before the switching-over of the announcement. Additionally, further switchings-over can be carried out which are advantageous for the attention of the driver. For example, switching off acoustically disturbing devices such as fans.
