    This paper presents an extension to the traditional room acoustic modelling methods allowing computer modelling of huge machinery in industrial spaces. The program in question is Odeon 3.0 Industrial and Odeon 3.0 Combined which allows the modelling of point sources, surface sources and line sources. Combining these three source types it is possible to model huge machinery in an easy and visually clear way. Traditionally room acoustic simulations have been aimed at auditorium acoustics. The aim of the simulations has been to model the room acoustic measuring setup consisting of an omnidirectional sound source and a microphone. This allows the comparison of simulated results with the ones measured in real rooms. However when simulating the acoustic environment in industrial rooms, the sound sources are often far from being point like, as they can be distributed over a large space in the room and may indeed contribute surfaces to the room. Examples of such sources could be ventilation tubes or the surfaces of two turbines as presented in this paper.
