Patent ID: 8379891

Claim:
A method for defining a speaker array processing algorithm, comprising: forming a primary objective function comprising: defining a target pattern that provides for high area volumes and low area volumes from a speaker array; forming a directivity pattern by combining a speaker output model and a speaker tolerance model; computing a sound field forming equation describing a modification made by one or more filters on the directivity pattern and modified sound wave output propagation data; and computing a directivity ratio based upon the target pattern as a ratio of an average power in a listening area to a total average power, the total average power defined as a square of the sound field forming equation; defining an unconstrained objective function based upon at least one of the primary objective function and one or more design constraints; applying an algorithm to the unconstrained objective function to extract one or more filter weights; and applying the one or more filter weights to one or more filters associated with the speaker array.
