Abstract

In this work, firstly a comparative analysis of the acoustic simulation programs RAYNOISE and ODEON was carried out. Secondly, the influence of the modeling accuracy on the convergence was analyzed. For the first objective, the same model was simulated with both programs. For the second objective, four geometric models of a room with different degrees of precision were generated, varying from 40 surfaces for the simplest model to 1,497 surfaces for the more complex model. Questions such as time for calculation, stability and power of the complex models, diffusion processing, convergence in the results, user interface facilities, etc. were analyzed.
