Abstract: This paper is concerned with sound radiation control of a loudspeaker that has omni-directional radiation in free field condition. When the loudspeaker is placed very close to flat surfaces, the reflections from the surfaces are as strong as the direct sounds and deteriorate the omni-directionality. This study assumes a proximate wall and attempts to analyze the effect of a reflection from the wall in terms of the directivity and to improve the omni-directionality by using a circular array of loudspeakers. For a given distance, weights for loudspeakers are calculated that make the sound radiation omni-directional in spite of the wall.
