Abstract
Provided are a system and method for evaluating sound system performance, comprising: representing an audience space is represented on a surface of a sphere. The sphere has a center that is substantially collocated with a center of a sound system. An efficiency of the sound system is calculated by determining an amount of energy produced by the sound system that reaches the audience space projected onto the sphere relative to a total amount of energy produced by the sound system. A metric is generated for a function by normalizing the efficiency by a ratio of an area of the audience space relative to a total area of the sphere to produce a score for the performance of the sound system.
