Patent ID: 7773768

Claim:
An acoustic design support apparatus comprising: a display; a speaker selection supporter that selects a desired speaker as a candidate for use in a given space based on shape information representing a shape of the space; a speaker mounting angle optimizer that calculates an optimal mounting direction of the selected speaker by selecting a mounting direction pattern which minimizes a degree of variation among sound pressure levels at a plurality of positions on a sound receiving surface defined in the space; and an acoustic parameter calculator that calculates a variety of acoustic parameters at sound receiving points within the space based on both of the shape information of the space and the optimal mounting direction of the speaker, wherein the speaker mounting angle optimizer sets a plurality of mounting direction patterns at intervals of a coarse horizontal angle and a coarse vertical angle and selects a plurality of candidates of mounting direction patterns from the plurality of mounting direction patterns, and resets a plurality of fine mounting direction patterns at intervals of a fine horizontal angle and a fine vertical angle around each of the candidates of the mounting direction patterns and selects one of the fine mounting direction patterns providing a minimum degree of variation of the sound pressure levels from among the plurality of the fine mounting direction patterns, as the optimal mounting direction of the speaker.
