Abstract: According to one embodiment, an acoustic control apparatus includes an acquisition unit, a detection unit, a correction unit, and an output unit. The acquisition unit acquires a first acoustic signal. The detection unit detects an information sound. When the detection unit detects the information sound, the correction unit corrects the first acoustic signal to a second acoustic signal by convoluting the first acoustic signal with a first function. The first function represents an acoustic transfer characteristic from a virtual position to a listening position. The virtual position is located along a first direction from the listening position. The output unit outputs the second acoustic signal.

Abstract: A first speaker radiates a first sound toward first and second listening points by a first sound signal. A second speaker radiates a second sound toward these points by a second sound signal. The first sound signal is generated by convolving a signal with a first filter coefficient. The second sound signal is generated by convolving the signal with a second filter coefficient. A nearer speaker to a virtual sound source is decided among the first and second speakers. The first and second filter coefficients are calculated so that a ratio of a first sound pressure of the first and second sounds at the first listening point to a second sound pressure thereof at the second listening point is equal to a target ratio. Among the first and second filter coefficients, based on one filter coefficient corresponding to the nearer speaker, the other filter coefficient corresponding to another speaker is calculated.
