Manufactured from high quality EPS (Expanded Polystyrene), the Trap Fuser is a unidirectional panel that controls sound reflections in two different ways – absorption and diffusion. Its hybrid structure allows sound energy to either be trapped in the cavities, or scattered by the plain surfaces. Usually applied for the treatment of mid or high frequencies, the Trap Fuser panel represents true acoustic science development. Designed for a range of frequencies between 630 Hz to 5KHz.
