Özet:

In order to model the sound propagation as adequately as possible in the closed space and its interaction with obstacles, the assessment of several excitation sources and the sound transmission through the obstacle should be taken into account, which is very important when the direct field of sound pressure is predominant if compared to the reflected field of sound pressure. In this work, the model of acoustic field which takes into account the excitation of several sources, sound propagation in the closed space and its full interaction with obstacles in the real conditions on the basis of finite element was created. To check the adequacy of the theoretical model and its potential to be applied in the design of noise reduction systems in real conditions, i.e., with several noise sources present at a time, the experiment was carried out, and its results were compared with the theoretical ones.
