The purpose of this paper is to develop a method to predict the sound intensity field in a room. First of all, the velocity potential and normal differential of that are calcurated for a specified room geometry using the integral equation method. Then, the sound intensity vectors are calcurated from the distribution of sound pressure and particle velocity. Some presentation ways of sound intensity field are compared if it is suitable for evaluating the distribution of it. So, it is found that the presentation using stereogram method is advantageous in that the total three dimensional distribution of sound intensity can be clearly recoenized. Thus the stereogram method is a good tool for interpretating the calculated acoustic intensity for acoustic room design.
