Controlling loud machinery noise and other job site noise requires more than a simple absorber. The powerful noise energy generated by construction work drove us to develop a barrier backing that has the density and mass to impede, and therefore control, the amount of noise that leaves the jobsite. This barrier backing is unique to the Noise Soaker panel and economically delivers a Sound Transmission Class rating of 33 (STC 33), measurably blocking sound well above any comparable alternative. Additionally, the absorptive site-facing quilted side of the Noise Soaker panels provides a Noise Reduction Coefficient (NRC) of 0.75 that absorbs noise energy, thereby reducing reflected noise within and around the jobsite. In comparison, sound waves will reflect off simple surfaces like plywood, resulting in unwanted noise bouncing through the job site and surrounding areas. Dual-purpose noise absorption and noise blocking Noise Soaker panels provide the best construction site noise control on the market.
