PROBLEM TO BE SOLVED: To bring sound quality in an acoustic system, especially in an automobile, into the best state in terms of dynamic space matching, using a simple method. SOLUTION: In this method, an acoustic space characteristic in a guest space especially in an automobile is detected by using a valid sound transmitter 1 to generate a test sound and to analyze a received evaluation sound. In this case, the test sound is transmitted to the masking area of a valid sound in terms of psychoacoustics. Preferably, before the transmission of the valid sound and the test sound, a valid sound analysis block 2 decides the masking area of a valid sound. |
