Journal of the Acoustical Society of America, 67(1), 206-213. doi: 10.1121/1.3837290001-4966http://hdl.handle.net/10919/52651Partially absorbing parallel surfaces can be the dominant acoustical feature of many rooms. The sound fields in such rooms are not diffuse, which causes difficulty in predicting sound pressure levels. A method is developed for predicting sound pressure levels in these rooms. It rests on the prediction of sound pressure levels caused by a nondirectional source of known sound power radiating between absorbing parallel planes. The development proceeds from a geometrical acoustics viewpoint. Good correlation has been found between predicted and measured levels in existing rooms having simple geometries.8 pagesapplication/pdfen-USIn CopyrightSound pressureAcoustic transmissionAcoustic wavesSound power levelsArticle - Refereedhttp://scitation.aip.org/content/asa/journal/jasa/67/1/10.1121/1.383729https://doi.org/10.1121/1.383729
