ABSTRACT:
In order to measure a sound characteristic in a sound space, measurement sound is outputted to the sound space. Measurement sound data of a predetermined time period, which is prepared in advance, is divided into plural block periods, and plural block sound data are generated. A reproduction process of reproducing the plural block sound data in the order forming the measurement sound data is executed plural times by shifting the block sound data reproduced first by one for each time. Thereby, the measurement sound is outputted. When the above reproduction process is executed plural times, detected sound data corresponding to the block sound data reproduced at the identical reproduction order for each time are operated, and a sound characteristic is determined. Thereby, it becomes possible to measure the sound characteristic in the period shorter than the measurement sound data of the predetermined time period.
