<p>To efficiently detect a standing wave generated in a room, a standing wave detection apparatus for detecting a standing wave in a predetermined space includes sound-receiving means (105) for receiving a sound generated from a sound source, storage means (102) for storing time series sound pressure level data acquired by the sound-receiving means (105) during movement along a path in the predetermined space, adjustment means (123) for adjusting the time series sound pressure level data based on an adjustment curve determined using the lower envelope of the stored time series sound pressure level data, and detection means (124) for detecting the extreme point of a standing wave in the predetermined space based on the adjusted time series sound pressure level data.</p> |
