Soundown QuietCore Panels are composite panels consisting of high quality marine plywood skins sandwiching an acoustic core. The plywood skins constrain the acoustic core resulting in a panel that is highly damped for its weight and thickness, especially, when compared to standard plywood. Standard QuietCore panels have skins ranging from 4mm to 12mm and cores of 4mm to 6mm. Normal applications use equal thickness skins around the acoustic core for the best panel bending stability. The make-up of the correct composite for your application will be based on the noise source, weight allowance and type of installation.
The composite construction of the QuietCore panels creates a panel that works in standard wood constructions and has the benefit of a constrained damping layer which enhances acoustic performance. The constrained damping layer acts to convert acoustic energy into small amounts of heat and dissipates it into the air instead of allowing noise to be transmitted into the accommodation spaces.
