PROBLEM TO BE SOLVED: To extract a feature quantity used for measuring the similarity of an impulse response.SOLUTION: A data storage unit 9 stores data related to a plurality of mutually different acoustic environments. An impulse response measurement unit 1 measures an impulse response of a user environment. A feature quantity calculation unit 2 calculates a feature quantity which shows percentage of rear part reverberation power of the impulse response of the user environment in the overall power. The feature quantity calculation unit 2 calculates a feature quantity which shows percentage of rear part reverberation power of the impulse response measured in the acoustic environment in the overall power. A data selection unit 3 selects data related to the acoustic environment corresponding to the user environment on the basis of distance between the feature quantity calculated from the impulse response of the user environment and the feature quantity calculated from the impulse response of the acoustic environment.SELECTED DRAWING: Figure 1
