• It is important to make a precise estimation of the sound pressure level distribution in a factory which contains many noise sources, such as machine tools, oil pressure equipment, etc. The sound pressure level in the factory varies because the sound sources do not always generate constant sound pressure by repetition of the working and resting of the machine tools. This paper deals with a simulation of the sound pressure level in the factory, which is analyzed with sound energy equations and the Monte Carlo method. Effects of the room constant, working ratio, frequency, deviation of sound power level, etc., on the sound pressure level are made clear.
