Apparatus and method for generating an acoustic radiation pattern
Disclosed are an apparatus and method for creating an acoustic radiation pattern, which may improve sound focusing performance to a target position. The acoustic radiation pattern creating apparatus may process an input signal which may be output through a speaker array in a room such that at least one vertical-directional reflected wave component of the input signal may overlap a direct sound of the input signal at the target position. Then, the acoustic radiation pattern creating apparatus may replicate the processed input signal by the number of output channels of the speaker array, and may process the replicated input signals such that the replicated input signals may form a predetermined radiation pattern in a horizontal direction in the room when the replicated input signals are output through the speaker array.
