PROBLEM TO BE SOLVED: To continuously listen to the voice of the same contents with a desired program which has been listened to thus far, even when an interrupt by announcement is initiated during the reception of the program of DAB(digital audio broadcasting). SOLUTION: While the desired program of DAB is received, the DAB and a simulcasted FM broadcasting program are searched for, by using the DAB-FM link function that the receiver for DAB is equipped with. When an interrupt is initiated by the announcement of DAB, the audio signals of the FM broadcast program of simulcasting and the DAB announcement are mixed at a specific rate by sound volume control circuits 13 and 25 and a mixing circuit 14 so that both the sounds can be listened to at the same time. The sound signal of the FM broadcast program is delayed by a delay circuit 24 to compensate the difference in data processing time between a DAB receiving circuit 10 and an FM-receiving circuit 20.
