ED - Rustighi, Emiliano T1 - Improvements on the statistical sound field description using waterhouse correction T2 - NOVEM 2009 - Noise and Vibration: Emerging Methods (Proceedings) N2 - The diffuse field assumption employed in Statistical Energy Analysis (SEA) and in statistical room acoustics is violated for source and receiver positions close to boundaries or discontinuities. An approach is suggested to include the correction made by Waterhouse based on spherical Bessel functions in SEA predictions. With this modification the SEA results will be augmented by a position dependence and an additional frequency dependence. The approach is extended and demonstrated for plate-like structures with different boundary conditions. The validity of the approach is confirmed by means of comparisons with modal analysis and finite element calculations.
