Method and apparatus for controlling distribution of spatial sound energy
A spatial sound energy (SSE) distribution control apparatus calculates filter coefficients for controlling distribution of the sound energy of an input signal, in consideration of a sound energy ratio between a reduction region for reducing transmission of a sound energy emitted through an array speaker and a concentration region for concentrating transmission of the sound energy and also in consideration of a sound energy efficiency of the concentration region. Also, the SSE distribution control apparatus determines an array size of a speaker in a case where the sound energy ratio is maximized, according to frequency variation of the input signal.
