Control early reflections, flutter echo and standing waves that cause resonant peaks.
The Primacoustic Stratus
Ceiling Cloud is an acoustical device that suspends above the recording
console to control early reflections, flutter echo and help eliminate
standing waves that cause resonant peaks in the critical mix position.
Once in place, you will immediately enjoy a more controlled and intimate
acoustic environment, larger sweet spot, and reduced ear fatigue.
Attractive
and very affordable, the Stratus acoustic cloud ships in kit-form and
is easily put together in minutes using a simple screw driver. The kit
includes a 2" thick, 24" x 48" acoustic panel made from high density 6lb
per cubic foot fiberglass and suspension hardware. The fiberglass is
encapsulated in a micromesh and the edges are resin treated to retain
the minute fibers. For an attractive appearance, the panel is covered in
an acoustically transparent fabric.
The suspension hardware
consists of two, light-weight, aluminum rails and "L" brackets that form
a rigid frame around the panel. To hang the Stratus, simply attach the
included picture wire to the frame. Hardware and fasteners for
sheet-rock ceilings are included in the kit. Typically, the Primacoustic
Stratus would be suspended above the console and clustered in an array
of three to span the width of your console.
The Stratus absorbs
sound energy by converting it to heat. Sound energy traveling via air
vibrations penetrates the panel causing the minute glass fibers to
vibrate and generate heat. This thermo-dynamic energy transfer
effectively absorbs directional sound energy and prevents it from
reflecting into the mix position.
By itself, the 2" thick
fiberglass panel is 100% effective for frequencies between 400Hz and
20kHz. To help control a broader frequency spectrum, the Stratus may be
angled to vary the air space between the Stratus and the ceiling. This
allows the backing surface to also absorb reflections off the ceiling.
For
years, acoustic clouds and canopies have been used to control sound.
They can be made of ridged material to reflect sound waves or soft
material to absorb it depending on their purpose.
In theaters,
reflective clouds are often visible in the form of hard, curved devices
that are arrayed and suspended above the stage. Theaters use theses
types of clouds to reflect sound back toward the stage so that the
musician can get a sense of intimacy. These reflective type acoustic
clouds provide the natural ambiance of a smaller room within a cavernous
hall, thus allowing the performer to better interact within the
acoustic environment.
Absorbing acoustic clouds, like the
Primacoustic Stratus, perform the opposite function: instead of
reflecting energy back into the space, the absorbing properties are used
to remove unwanted reflections. Basic forms of these devices are known
as acoustic baffles (or flags) and are often used in highly reflective
environments such as swimming pools, bottling plants, printing presses
and other commercial installations where controlling echo or reducing
the reverberant time can make the workplace a more comfortable and safe
place.
The Primacoustic Stratus is a more elegant solution and is
the preferred choice in environments such as recording studios where
acoustic performance is as important as esthetics. Acoustic clouds play
an important role in studio design as they control the powerful primary
reflections that originate from the monitors and bounce off the ceiling
and console. These primary reflections combine with the direct sound of
the loudspeaker and cause phase cancellation. Furthermore, parallel
surfaces such as a floor and ceiling cause standing waves to exist which
can introduce a resonant peak in the primary listening area.
