Investigation of adequacy of the acoustical field model

open access: yes, 2009
This 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
