Resumen de Non-plane reflecting surfaces in room acoustics
Mezhlum A. Sumbatyan, Nikolay V. Boyev
Very often the spaces considered in the ambit of room acoustics possess non-pane reflecting surfaces (Baroque-style constructions, Orthodox churches, etc). The nowadays approaches to simulate such reflecting surfaces operate with them like with a set of plane patches globally forming the real crooked surface. This technique implies that the wave interaction with the crooked surface is locally the same as in the case of purely plane surface that is not correct. In the present work we give correct formulas for acoustic ray interaction with arbitrary smooth non-plane reflecting surfaces and demonstrate the application of these theoretical results by some test examples.
