Abstract

The sound pressure level distributrion down a long, narrow hallway due to a sound source at one end does not decrease linearly along the length of the hall. This characteristic may be due to the changing behaviour of scattering that occurs down the length of the hallway, which is distance- and angle-dependent. A new scatteing method that incorpoates these effects has been implemented in the room acoustic computer modeling program, ODEON [C. L. Christensen and J. H. Rindel, Forum Acusticum, Budapest (2005)]. A comparison of the results from an ODEON model with real-world measurements along a long, narrow hallway on the campus of the Technical Unoversity of Denmark is provided in this paper.
