SIMULATION OF INDUSTRIAL SOUND ABSORPTION THROUGH VEGETABLE PANELS
The paper contains the simulation for the study regarding the diminish and sound absorbtion into industrial hall. The indoor plants have the possibility to absorb, to reflect, and to diffract the sound waves. They are given into industrial hall, where is an industrial equipment that produses sound pollution in the strong way. In this situation it is necessary to establish what are the possibility to diminish this pollution, and we consider that it is possible using the plane formed with plants. They are the vegetable with the knowen sound characteristics as: sound absorbtion, and sound transmition. For this study was necessary to use the Matlab program packge in Simulink for the panel formed with bark or Ficus Benjamina tree (bush).
