Apparatus for reproducting wave field using loudspeaker array and the method thereof

摘要

Provided is an apparatus and method for reproducing a wave field using a loudspeaker array. A loudspeaker array may be configured in front of and behind a listener, and a wave field synthesis rendering and a three-dimensional sound image localization rendering may be performed based on a position of a sound source.

主权项

1. An apparatus reproducing a wave field, comprising:
a sound source position analysis unit to determine a position of a sound source by analyzing sound image localization information; a rendering unit to output a wave field synthesis signal by performing a wave field synthesis rendering for the sound source based on the determined position of the sound source; a first plurality of loudspeakers to be arranged in at least one back row and to reproduce the wave field synthesis signal; and a second plurality of loudspeakers to be arranged in at least two front rows and to reproduce a wave field synthesis signal adjusted based on a sound pressure ratio between the at least two front rows of the second plurality of loudspeakers, selected as being arranged in a vertical direction, to localize a virtual sound source based on the sound pressure ratio, and wherein the at least two front rows of the second plurality of loudspeakers have directivity directed to a listener.
