Investigation of adequacy of the acoustical field model
AbstractThis work used the 2D model to analyze the pos-sibility to model several excitation sources acting at the same time in different harmonic frequencies. The obtained results of the theoretical experiment were compared to the results of practical experiment. The adequacy of the acous-tic field’s model formed on the basis of the finite elements to the real acoustic field was analyzed. Results showed that using the theoretical model created on the basis of FEM it is possible to model the acoustic excitation that appears in real conditions and to evaluate the noise level in particular environment.
