1. An acoustic apparatus, comprising:
- obtaining means for obtaining impulse response data between at least one speaker and a microphone;
computation means for computing step response data by integrating the impulse response data obtained by the obtaining-means; and
determination means for determining 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.
