Solid Impact Flow noise control
Most of the manufacturer who work with flow solid granule, resin pallet, plant seed, they need big fan or blower to send the solid through pipe line. Impact noise to the pipe wall make very loud noise and radiate all over the area. This is not only harm to the operator who works in the area, it also create noise pollution to the neighbor who stay closed to the factory.
Acoustic pipe insulation that present both structure-borne noise and air borne nose can handle this impact flow noise in the pipeline. To calculate the collect insertion loss , it is necessary to understand the characteristic of the pipe wall, noise from the blower itself, and propagation noise to the area. Combination of those three noise control, can reduce noise to the certain level in the regulation.
