A Uniquely Organic Shape With the Waveform Bicubic Diffuser

Waveform Bicubic
The Waveform Bicubic is a unique diffuser that is customizable and suitable for many applications.

Your first mental image of an auditorium, whether intended for musical performance or speech, likely includes the image of high ceilings. There are a number of reasons pertaining to logistics, performance, and sound quality that necessitate high ceilings (large room volume)—but that brings along with it issues that must be addressed. Untreated high ceilings lead to high reverberation times and audible echoes that degrade the acoustical performance of the space, whereas simple treatments utilizing absorption remove too much of the sound energy and which leads to a space that does not support the intended use. That’s where the Waveform Bicubic comes in: a diffuser capable of being arrayed to increase speech intelligibility and enhance musical clarity.

Customizable by Design

The Waveform Bicubic is intended to work for a number of applications. Fabricated from glass fiber reinforced Gypsum, the panels can be painted to match any interior design needs. Additionally, the size of the panels can be customized to match project-specific needs, expanding the possibilities even more. It’s an ideal overhead canopy or even wall-mounted panel that works well in all kinds of spaces—from auditoriums to worship spaces. Now it is available in both the original 8-3/8” deep design as well as a new 6-1/8” deep design for projects with shallower depth requirements. An asymmetric surface, which follows the state of the art in sound diffusion technology today, all sides terminate identically to allow for a variety of mounting configurations.

Organic Shapes

The first thing one may notice about the Waveform Bicubic is its aesthetically organic design. This idea has been seen in practice before where curved panels are used in canopies instead of flat ones so as to provide a uniform scattering of reflected energy towards the audience. The Waveform Bicubic improves upon this idea by integrated a research-backed design that offers both spatial and temporal scattering of the energy.

Reducing Periodicity Effects

Typically, multiple canopy panels are put together in an array that is intended to scatter energy towards the audience. However, a phenomenon called periodicity occurs when repeating surface pattern occur in an array, which can alter sound levels in certain spots due to the unoptimized nature of traditional canopy panels. The Waveform Bicubic was developed using a shape optimization algorithm to produce the ideal redistribution of sound and create an ideal experience for audience members and performers alike.
