Silent Running is made to stop structure borne noises. These come from noisy areas in places such as duct work, fan shrouds, automobiles, generator covers, and engine rooms to name a few. Silent Running coatings reduce unwanted noise by absorbing the vibration causing the noise.
The old way of removing unwanted noise was to add heavy asphalt mats to the metal panels. Believe it or not, this is still done today. What these heavy mats do is add mass to the panel, often as much as the panel itself. This doesn’t remove the vibration; it just lowers the intensity.
