Help control noise pollution with the innovative QuietSite™ Noise Barriers, which absorbs and reflects sound to reduce the perceived noise level (dBA). Noise in the workplace (occupational noise) not only poses a safety risk to work crews, but also affects the public near job sites. These sound barriers will dampen common construction noises by up to half, changing the perceived sound of a 90 lb. jackhammer breaking up concrete, to the dBA to that of a household blender. These noise barriers are effective in controlling the noise and allow compliance based on the state or local noise ordinance.
