Dust removal polished tank acoustic screen design considerations

Precipitation polished tank acoustic screen design considerations (1) grinding tank to avoid lateral diffraction, acoustic screen should be greater than the length of the sound source length of 5 times. (2) dust polished tank acoustic screen height requirement is higher than the sound source. (3) dust polished tank acoustic screen should be close to the source, if the condition allows, the best layout, the area around the acoustic screen around the machine and make it open sound insulation cover. (4) dust polished tank for barrier sound insulation, the biggest attenuation in practical application, it is difficult to more than 25 db, so acoustic screen are usually only used in some cannot use the sound insulation cover machinery, equipment and some sound volume of noise reduction is not high. (5) dust if polished tank made from rigid material acoustic screen, the side facing the sound source of acoustic screen should add with sound absorption material, can improve the effect of sound insulation. 6 dust acoustic screen height and to determine grinding ark, the noise attenuation is roughly constant, so the sound insulation quantity of selected materials acoustic screen from time to tome reverberation room is particularly important should be compatible with the R value, too large value of R is not necessary to 7 dust acoustic screen if polished tank for activities, try to reduce the screen, the gaps between the screen and the screen with the ground, in case of leakage.
