A Microcomputer Program for Central Loudspeaker Array Design
A microcomputer program is described which accurately calculates the direct-field SPL at points on a seating area generated by an arbitrary configuration of loudspeakers. The program solves inverse square losses as seen through the loudspeaker's directional pattern at up to 230 points on the searing plane. When multiple loudspeakers are used, their coverage patterns are merged by two strategies: phasor summation takes into account interference phenomena, while non-phasor combination provides the maximum envelope of response that can be expected of the combination of loudspeakers. When acoustical data is provided, direct-to-reverberant ratios can be calculated, and estimates of intelligibility, using the method of Peutz, can be made. A graphics portion of the program provides front, side, and top orthographic views of the loudspeaker array.
