ABSTRACT:
An acoustic apparatus includes an obtaining section configured to obtain impulse response data between at least one speaker and a microphone; a computation section configured to compute step response data by integrating the impulse response data obtained by the obtaining section; and a determination section configured to determine a connection polarity of the speaker in accordance with the size relationship of areas of a region on the positive side and a region on the negative side of the step response data in a determination segment of a predetermined time width in which a rise point of the step response is a starting point.
