Designing and Testing of Noise Cancellation Chamber

Abstract

The article deals with description of chamber designing in which spraying of coating on product by explosion method is taking place. Specific features of this production is in creating of high level noise, necessity of quick removal of formed dust and poisonous gases and simultaneous supply of fresh air. To solve this problem calculation of noise absorbing materials of multilayer constructions of walls and ventilation chamber system were carried out. Effective decision of walls construction with ventilation channels in its inner cavity was obtained. Results of three-dimensional modelling and natural test of noise-cancelling ventilation chamber system work were presented.
