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.
