Abstract
The present disclosure relates to an acoustic control apparatus applied to a loudspeaker system including first to Mth loudspeakers. In one implementation, the apparatus includes first to Mth control filters. The first to Mth control filters convolve a first input sound signal with first to Mth control filter coefficients to generate first to Mth sound signals. The first to Mth loudspeakers produce sounds based on the first to Mth sound signals. The second to Mth control filter coefficients are calculated based on the first control filter coefficient and at least one first acoustic transfer function set from the first to Mth loudspeakers to at least one first one-ear position, such that a spatial average of at least one sound pressure of the sounds at the at least one first one-ear position comes close to 0.
