A sound field adjusting device reproduces signals from plural speaker pairs arranged in an acoustic space. The device supplies signals to the plural speakers, gives different delays for the respective frequency bands to the signals supplied to at least to a proximity speaker pair which is a speaker pair closest to a listening position among the plural speakers, and gives a delay of a constant delay amount regardless of the frequency band to the speaker pairs other than the speaker pair to which the delays of different delay amounts for the respective frequency bands are given. In this case, the sound field adjusting device does not perform level adjustment, and the sound field adjustment is performed by only adjusting the delay amounts. Therefore, deterioration of sound pressure balance at the position other than the listening position can be avoided, and sound pressure balance at the listening position improved. |
