damped noise barrier
These properties make Subdue M a slimmer and higher performing composite panel over Subdue L. The product is suited to medium privacy areas such as areas adjoining engine rooms, VIP rooms, master state rooms. It’s typically used in interior applications such as lightweight wall, ceiling and floor construction and in marine, commercial and rail construction.
The ‘M’ category of ‘Subdue’ panels includes inner cores with densities from 1000 kg/m³ up to 2000 kg/m³.
Coincidence dip is a common phenomenon in lightweight panels, that adversely impacts the sound transmission loss performance in materials such as timber, plywood, sheet metal, low density rigid foams and hollow core walls. However, Subdue’s unique multi layered composition with its inner core layer, shifts the coincidence dip to frequencies limiting its impact, thereby maintaining the performance of panels. Subdue M works by reflecting, absorbing and damping the vibration and transmission of sound through walls, ceilings and floors, reducing the critical frequencies generated from mechanical equipment, engine noise and electronic audio devices.
