The first two-dimensional QRD – ideal for Home Theatres and Project Studios.
Conventional acoustic treatments have relied on absorption for reflection control Unfortunately, this can “deaden” the room and make it unsuitable for speech and music. Diffusive ceilings are one of the most effective ways to simultaneously control room reflections and provide a natural ambience. The Hemiffusor uniformly scatters sound arriving from any direction, providing ideal distribution and coverage.
The unique shape creates an attractive, visually interesting acoustical surface.
Specular reflections from flat, hard surfaces cause strong reflections which corrupt speech intelligibility and degrade music quality. Typically, fabric wrapped panels are sued to control interfering reflections, with the undesirable side effect of deadening the space.
The Hemiffusor is the first and most affordable 2D QRD. it offers twice the reflection attenuation of the 1D QRD, because it uniformly scatters sound into a hemisphere. The Hemiffusor provides uniform, omnidirectional, broad bandwidth diffusion in an attractive ceiling or wall design element.
