Abstract
According to one embodiment, an acoustic control apparatus includes a first calculator, a second calculator, and a first setting unit. The first calculator calculates a first relationship established between acoustic filter coefficients, based on sounds emitted from sound sources. The second calculator calculates a second relationship established between the acoustic filter coefficients by matching a first sound pressure ratio with a second sound pressure ratio, in a complex sound pressure ratio between ears of a user who desires the sound information. The first setting unit sets an acoustic filter coefficient corresponding to each of the sound sources, based on the first relationship and the second relationship.
