摘要： Resonant frequencies f2 and f3 detected in a resonant space are determined as center frequencies of a dip. Based on measurement values at a speaker and a microphone in the resonant space, a basic amplitude frequency characteristic Ca and a target amplitude frequency characteristic Cd are found. A smoothness degree on a frequency axis is larger in the target amplitude frequency characteristic Cd than the basic amplitude frequency characteristic Ca. A damping level and quality factor of the dip are determined based on a difference between the basic amplitude frequency characteristic Ca and the target amplitude frequency characteristic Cd in the center frequencies f2 and f3 of the dip and frequencies near the center frequencies.

摘要： An improved acoustic characteristic adjustment device comprises signal processing units including high frequency convolution arithmetic sections, low frequency convolution arithmetic sections, and delay sections. The device further comprises: an operation section from which a listener inputs a target characteristic in order to adjust a desired acoustic characteristic; an impulse characteristic control section; and a delay time control section. The impulse characteristic control section calculates impulse response data to effect convolution arithmetics. The delay time control section calculates alignment delay times necessary for sounds emitted from the speakers to reach a listening position. The delay time control section also calculates correction times for compensating various phase deviations. Times obtained by correcting the alignment delay times with the correction times are set as the delay times of the delay sections, respectively.
