  • Abstract Beam tracing in computer graphics, builds the model of the light paths and produces the light rendering effect by tracing the light that intersects the surface of the model. Sound, like light, is a kind of wave. It can also intersect the surface of the model and produce transmission, reflection, refraction, diffraction. If we treat sound as light, using beam tracing, we can get the model of the sound path.
    This research applies beam tracing in architectural acoustics. The prototype system considers the geometry of the building, the position of the source and receiver, and the acoustic properties of the sound transmission (the sound absorption coefficient of the walls and the temperature of the environment). The system then builds the beam tree by beam tracing, and finds all possible paths of the transmission and reflection. All sound paths are then traced to compute the sound obtained by the receiver. By considering many receivers, we draw the distribution of the sound energy and discuss the effects of the different architectural structure.
    Key Words: Beam Tracing, Architectural Acoustics, Beam Tree, Reverberation.
