Abstract: PROBLEM TO BE SOLVED: To provide the automatic adjustment device in a multi-channel acoustic system and the method for adjusting a reproduction state so as to create an optimum listening environment in the listening environment of an audio equipment for a household or for an individual. SOLUTION: White noises produced by the transmission characteristic measurement part 10 of the system are produced from respective speakers 12 and transmission signals from the respective speakers 12 are collected through the column of microphones 11 at a listening position and transmitted to a transmission function calculation part 10. The transmission function calculation part 10 calculates transmission characteristics between the respective speakers and the listening position by using generation signals and collecting signals and adjusts the characteristics of respective acoustic channels so as to make all the transmission characteristics between the respective speakers and the listening position be similar. Then, a channel by the mounted speaker and a virtual image channel generated by using a transmission function beforehand are synthesized and reproduced.
