Patent ID: 8332060

Claim:
An acoustic design support apparatus for calculating optimal mounting angles of a plurality of speaker units included in an array speaker for use in a given space, the apparatus comprising: a pattern setter that sets a plurality of mounting angle patterns, each mounting angle pattern corresponding to a combination of specific mounting angles of the speaker units; a sound pressure level variation degree calculator that performs, for each of the set mounting angle patterns, an axis point position calculation process for calculating positions of axis points at which a sound receiving surface defined in the space intersects axis lines of the speaker units at the specific mounting angles, an equalizer parameter calculation process for determining equalizer parameters of the speaker units which minimize a degree of variation among frequency characteristics of sound pressure levels at the axis points, and a sound pressure level variation degree calculation process for obtaining a degree of variation among the sound pressure levels at a plurality of positions previously set on the sound receiving surface based on the determined equalizer parameters and frequency characteristics of each speaker unit; and a pattern selector that selects one of the set mounting angle patterns, which minimizes the degree of variation of the sound pressure levels at the plurality of the positions, as an optimal mounting angle pattern which determines the mounting angles of the speaker units of the array speaker.
