Home Wood Waveform™ Monoradial W Waveform™ Monoradial W Product Detail
Waveform™ Monoradial W

The Waveform™ Monoradial-W is a timeless shape in architectural acoustics, used in auditoriums to blend the direct and reflected sound to increase intelligibility and/or enhance musical clarity and intimacy. The Waveform™ Monoradial-W is a Class A fire rated, FSC certified unit with no added urea formaldehyde. When absorptive material is placed into the rear cavity of the assembled unit, significant reverberation time reduction can also be accomplished.

The Waveform™ Monoradial-W comes in a wide variety of finishes, including wood veneer, laminates, melamine coatings and painted surfaces. See some of the options displayed under the Finishes tab below.

The Waveform™ Monoradial-W is designed to hang freely, each unit a separate "cloud", or bolted together to create a canopy. They can also be configured for direct mounting to a wall or ceiling using the appropriate wood blocking. See details below under the Drawings tab.

Waveform® Monoradial-W 1D Wood Sound Diffuser
The Waveform® Monoradial-W is a timeless, natural wood shape in architectural acoustics, used in auditoriums both as overhead canopies, in order to better blend the direct and reflected sound, and along walls to provide scattered sound to the audience. A canopy design approach will increase intelligibility, enhance musical clarity and improve intimacy. Typically, curved canopy arrays are used instead of flat to provide not only the needed early reflections, but also provide some scattering of the reflected energy to more uniformly address a broader selection of the audience.

In auditoria, in order to have a sufficient volume of space for various logistical, performance and sound requirements inherent of the intended use, the design demands that there be high ceilings. If left untreated, the reflections from a far, hard ceiling can degrade the acoustical performance of the space. If the ceiling is simply treated with absorption to mitigate the disturbing reflections, then more energy, energy that is important and useful, is being removed from the space than needed. This is especially true in regards to high frequency energy. In the end, an absorptive approach means that there would be less acoustical support coming from above the audience which if appropriately addressed can increase intelligibility, enhance musical clarity and improve intimacy as noted above.

Overhead canopies are suspended below the constructed ceiling in auditoriums to both improve and provide control for the acoustics of the space. When properly oriented, canopy arrays will provide desirable early reflections while helping to maintain the required reverberation time. This can be accomplished by incorporating absorption into the rear cavity of the unit. Flat panel arrays are sometimes used for economy; however, these can potentially provide non-uniform sound to the audience. This issue is solved simply by curving and orienting the panels to provide sound diffusion. The simplest approach to curving the panels is a single curvature panel RPG calls the Monoradial™.
