ACOUSTICAL GOALS

Great sound is our passion, not just an incidental (and unpredictable) byproduct of an attractive “theme” treatment system.

For your reference, we have included a very general overview of how we approach these common applications of the ELiTE-CFS.

RESIDENTIAL THEATERS/CONTROL ROOM/CRITICAL LISTENING ENVIRONMENTS

Every entertainment space is different, and every client has their own opinion as to what is the perfect sound. However,

we have established a very general set of parameters, or goals, we work toward, in the typical Residential Theater or audiophile

setting.

In most Residential Theater rooms, we strive to:

•Minimizeearlyreflections;reflectionsthatarriveatthemainlisteningpositionwithinthefirst50to80milliseconds.

Conforming to the “Haas Criteria” is usually safe.

•Minimizelatereflectionanomaliessuchasflutterechoes.Thiscanbeaccomplishedwithabsorptionand/ordiffusion.Any

late reflection anomalies should be at least 15-20 dB below the direct sound in order to be unnoticeable.

•Minimizeasmanylowfrequencyissuesasisfeasible,dependingonthephysicalcharacteristicsoftheroom,anddécor

considerations. In general, ± 3 dB from 100 Hz to 300 Hz and ± 5 dB from 20Hz to 300Hz are usually be considered

reasonable goals, but will depend on size of room, sound source selection, budget, etc. – in many cases these frequency

ranges have frequency response curves much better than these figures.

“Excellent”.

CONFERENCE/PRESENTATION ROOMS

In this type of application, the acoustical treatment is intended to provide optimal speech intelligibility. Although many of the

criteria may be similar to those listed above, a focus on absorption is typical in order to minimize reflections of all kinds.

SANCTUARIES AND OTHER LARGE SPACES

Very large rooms typically have long reverberation times (RT’s) and for some applications, this is acceptable. However,

as musical styles and sound reinforcement evolve, this excessive ambience may become problematic. We work with the dealer

and client to determine the appropriate acoustical goals, then base our treatment proposals on proven acoustical theory,

extensive computer modeling (such as Fitzroy calculations) and in some cases, onsite measurement. The end result is a room

that is perfectly tuned for its intended use. ELiTE-CFS is also an ideal solution for implementing a fabric covering over speaker

enclosures, thus minimizing their overall impact on the aesthetics of a House of Worship.
