Abstract:
1. A sound characteristic measuring device comprising: a measurement sound output unit which outputs measurement sound to a sound space; a detecting unit which collects the measurement sound in the sound space and outputs correspondent detected sound data; and a characteristic determining unit which determines a sound characteristic in the sound space based on the detected sound data, wherein the measurement sound output unit includes: a block sound data generating unit which divides measurement sound data of a predetermined time period into plural block periods and generates plural block sound data; and a reproduction processing unit which executes a reproduction process of reproducing the plural block sound data in a reproduction order pattern forming the measurement sound data, for all patterns of the reproduction order obtained by shifting block sound data reproduced first by one, to output the measurement sound, and wherein the characteristic determining unit operates the detected sound data corresponding to the block sound data reproduced at an identical reproduction order during each reproduction process, and determines the sound characteristic.
