Waveform Spline G3

Spline G3 Feature Image

Overview

The Waveform Spline G3 represents the continuing evolution in architectural acoustics toward quantifiable, organic shapes. It is designed to blend the direct and reflected sound to increase intelligibility and/or enhance musical clarity and intimacy in performance spaces such as auditoria, band rooms and choral rooms. One of the most powerful one dimensional sound diffusers available today, the asymmetric Spline G3 can be arrayed to reduce periodicity effects.

Finish

The Waveform Spline G3 units are typically provided with a paint ready surface for onsite application, however units can be factory color matched to any paint color specification.

Installation

The units are 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.

The Waveform Spline G3 represents the evolution in architectural acoustics toward quantifiable, organic, shapes; 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 scattering of the reflected energy to more uniformly address a broader selection of the audience.

 

 

 

 

Problem

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.

Solution

Overhead canopies are suspended below the constructed ceiling in auditoriums to both improve and control 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 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 most effective approach to curving the panels is in optimizing multiple radii into a single, asymmetric element which can then be arrayed using sequencing techniques that avoid periodicity.

Features

  • Offers an attractive, acoustically optimized canopy and wall treatment for large, performance driven spaces for music, theater and lecture.
  • Broad bandwidth sound diffusion can be arrayed into very large areas
  • Units come in standard size of 47-3/4″ x 47-3/4″
  • Choose from any commercially available paint color.
  • Stable, non-combustible acoustical glass reinforced gypsum is an excellent choice for commercial projects and offers LEED points.
  • Asymmetric by design and patented, the Waveform Spline G3 can be array optimized to reduce periodicity effects.
  • Canopy layouts can be sequence optimized, along the length of the hall for both height and tilt, for further improvement in coverage and scattering.

The Waveform Spline G3 units are typically provided with a paint ready surface for onsite application, however units can be factory color matched to any paint color specification.
