Document Type and Number:
Japanese Patent JP6452377
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control a sound field so that important sound information can be heard independently for each region, in a closed space.SOLUTION: A speaker arrangement selection unit 400 for selecting a plurality of speakers for use in sound field control in a closed space includes a first speaker selection unit 410 for selecting a speaker of high linear independence for a predetermined region, out of existing speakers, and a second speaker selection unit 420 for selecting a position of high linear independence for the predetermined region, as the installation position of at least one additional speaker added to the existing speakers.SELECTED DRAWING: Figure 3
