Loudspeaker Coverage by Architectural Mapping
A new technique uses rectangular-to-spherical coordinate transforms to generate an angular map, displaying auditorium seating in latitude and longitude angles as seen by the loudspeaker. Loudspeaker coverage and inverse-square losses can be instantly determined by this method, and intelligibility can be calculated easily for an entire area of seating. Loudspeaker radiation angular contours are presented for a number of high-frequency horns, as well as software for automatic computation of map point locations.
