Image Source Model for Loudspeaker Enclosure

An application of the image source model for computing the interior sound field of a loudspeaker enclosure is presented. The image source model allows computing the effects of individual reflections, enclosure modes, etc. on the response of the speakers in an efficient manner for rectangular enclosures, both sealed and ported. The effect of the absorbent material can be included without excessively adding the computational complexity. As the model makes no assumptions on the enclosure size, it can be equally well applied for modeling e.g. in-wall loudspeakers, where a combined model of room and loudspeaker responses can be developed.
