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.
Claims8
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.
A connection polarity determination method comprising:
- obtaining impulse response data between at least one speaker and a microphone;
- computing step response data by integrating the obtained impulse response data;
- and
- 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.
A recording medium having stored thereon a connection polarity determination program for enabling a computer installed in an acoustic apparatus to perform a process for determining connection polarity, the process comprising:
