Abstract: An array speaker system canceling non-uniform radiation patterns and a method for implementing the same are provided. The method for canceling non-uniform radiation patterns includes predicting radiation patterns in an array speaker with respect to input signals, generating cancellation signals with respect to at least one region corresponding to non-uniform radiation patterns of the predicted radiation patterns, synthesizing the input signals and the cancellation signals, and outputting the synthesized signals to the array speaker. Sound signals from which non-uniform radiation patterns having distorted sound are cancelled such that a stable sound field having uniform radiation characteristics may be obtained and provided to a listener.

Abstract: A method and apparatus for compensating for a near-field effect in a speaker array system is provided. The method includes generating a virtual sound signal at a position, which is separated from a speaker array by a predetermined distance, based on an input sound signal, and outputting the generated virtual sound signal using the speaker array. Therefore, the near-field effect, in which a sound radiated from a speaker array is distorted to have non-uniform radiation characteristics near the speaker array, can be compensated for. Consequently, the method and apparatus can provide a stable sound field, into which non-uniform radiation characteristics uniformly converge, to a listener.
