Wavebar® dBX is a high performance, flexible, massloaded, polymer noise barrier offering superior acoustic transmission loss. dBX represents the latest in alternative noise barrier technology using recycled polymers that are halogen-free. It was developed to meet market noise reduction requirements for the domestic, commercial, industrial and automotive markets. This high performing product was engineered by Pyrotek to achieve a self extinguishing, low smoke emission, thin, strong and flexible product. These properties give dBX added strength, high transmission loss and fire rating. The facing also makes it easy to bond onto other substrates using matching tape adhesive or equivalent. Stiff lightweight panel constructions, such as plasterboard, drywall, plywood and hollow core walls, typically have coincidence dip resonance which allows noise to transmit through a construction. The coincidence dip is dependent on the material’s stiffness and thickness and occurs at the point where the sound transmitted through the structure matches the natural frequency of the panel. dBX shifts the coincidence dip to frequencies limiting its impact, thereby maintaining the performance of the product. The thin, dense mass barrier reflects and absorbs the transmission of sound through walls, ceilings and floors, reducing the critical frequencies generated from mechanical equipment, engine noise and electronic audio technologies such as radio and television.
