Laboratory testing demonstrates that this noise control suite reduces the A-weighted sound power level of the vibrating screen by 6 dB. To provide a comparison to laboratory results and prove durability field testing of two noise controls was performed on a vibrating screen in a working coal preparation plant
Noise controls for vibrating screen mechanisms. 2012-08-30 measurements on a vibrating screen at their Office of Mine Safety and Health Research laboratory in Pittsburgh. The results show that the entire screen contributes to noise below 1 kH and the vibration mechanism housings are
The exposure to noise can be reduced by eliminating the source of noise if possible substituting the source with a quieter one applying engineering modifications using administrative controls and by using protective equipment. The best way to reduce exposure to noise is to engineer it out at the design stage
