For best results you must model your room AND your speakers, understand how they interact, and use those measurements to design the acoustic treatment scheme.

Our Acoustic Room Treatment service is one of the  most sophisticated in the industry. We use commercially manufactured products as well as custom-designed acoustic treatments. And our designs take into account many elements: bass resonances, speaker boundary interference cancellations, early reflections, and late reflections.

In existing rooms, we measure bass resonances. In new rooms, we model bass resonances using sophisticated boundary element modeling (BEM) techniques, not just simple room mode calculators. Acoustic treatment is effective at dealing with 100-300Hz issues but becomes less effective below 100Hz.

We recommend our Low Frequency Optimization service to deal with these low bass issues.

Early reflections created by sound bouncing off the major boundaries in the room–side walls, ceiling, floor, front and back walls—can severely impact sound quality. Our approach is to use our in-house ray tracing tools, alongside acoustic measurements in existing rooms, to reveal the level and direction of each reflection. We supplement this with analysis of speaker off-axis response measurements that reveal the spectral relationship of the reflected and direct sounds. From there we assign psychoacoustic significance to each reflection and determine whether to treat through absorption, diffusion, or a hybrid approach, or perhaps to simply leave it untreated and reflective.

Late reflections consist of a multitude of low-level reflections, and are often referred to as reverberant sound. This sound is important for our perception of spaciousness, envelopment, and overall tonal balance. We use measurements and modeling to ensure consistency in the spectral balance of the late reflected field.
