Panel for diffusion control

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. In many practical applications, especially those that require a large area of diffusion treatment, it is common to repeat a same diffuser, so as to introduce periodicity into a sequence. This will concentrate the reflection energy in the diffraction orders of the grating and result in a narrower diffusion pattern. The innovation with the Trap Fuser RD lies in the freedom to position the panel’s two halves and create random sequences. By rotating these diffusers in different directions, you can achieve combinations of patterns that are not only appealing to the eye but also extremely efficient when the aim is diffusing sound in a particular area. In order to increase diffusion an upgrade made of wood plaques can be purchased separately. You may also install this product with the new VicFix J Profile fixation system using VicFix Base, sold separately.
