4 Easy Steps To Own The Industry’s Finest Acoustical Room System:
CinemaTech’s Acoustic Room Systems (also known as ARS) provides a complete solution for an acoustically superior yet aesthetically
pleasing Home Theater environment. No other acoustical product on the market can offer this level of performance in such a low-profile
panel. CinemaTech’s ARS provides a fine-tuned acoustical environment that will diminish distracting noises from outside the theater and
allow the articulation and intelligibility of the movie sound track to be clean, crisp, and balanced. This is achieved while maintaining
complete aesthetic appeal and beauty of the Custom Home Theater.
Step 1
Starting from a finished room, including sheetrock, a highly trained ARS
installation professional will arrive on site to install theater elements such
as columns and architectural woodwork. This portion is only applicable
when purchasing a full CinemaTech Custom Theater Design.
Step 2
Next the CinemaTech ARS installer will apply the 1 ¼” deep fabric retainer
that will provide the framework for CinemaTech’s ARS acoustical panels
and acoustically transparent fabric.
Step 3
Reversible diaphragmatic panels and high frequency diffusers are then
applied directly to the sheetrock according to the strict specifications
from the detailed modeling diagram based on our acoustical analysis.
This modeling diagram is the culmination of several factors including
the type and placement of speakers, the intended “sweet spot” and the
decorative components within the room.
Step 4
After a couple of days (depending on the size and intricacies of the room)
the acoustical treatment is hidden forever by the acoustically transparent
fabric and finishing touches that are applied to provide a grandiose theater
environment with acoustical performance that any audiophile will envy.

Acoustics You Can Trust
The single most important aspect of CinemaTech’s ARS
system is that we can prove its worth. There are many alternative products on the market that “claim” to improve
acoustical performance as a result of their products, or
so called systems, by simply applying fiberglass to the
walls of your theater. However, this is not the solution for
an acoustically accurate environment. The reality is that
the majority of these systems cannot prove their product’s
results and many actual decrease the performance of the
room.
CinemaTech’s ARS system was originally developed and
tested at the state-of-the-art Owens Corning Acoustical
Research Laboratory in Granville, Ohio. A large part of
the industry’s understanding of acoustics has been drawn
from this laboratory. Most acoustical references and textbooks have numerous references to the information gathered at this nationally accredited and internationally recognized testing facility.
The products that make up CinemaTech’s ARS are Owens Corning’s best solution for acoustical room treatment.
With millions invested to research, develop, and most importantly, test these products, CinemaTech’s ARS system
is proud to be one of the few that can prove its effectiveness.
These extraordinary acoustical products are available exclusively through CinemaTech, Inc. and are accompanied
with unmatched acoustical expertise and advanced proprietary computer modeling to meet the acoustical needs
of each individual room.
“The Room: The forgotten component... the listening room contributes as much to what you hear from
the system as any of its
components.”
“...the physical attributes of
listening rooms are every bit as
important as the audio
equipment involved.”
“The room is which music is
reproduced has a profound
effect on sound quality.”

ARS Reversible Acoustic Panels
The heart of CinemaTech’s ARS system is the patented,
reversible acoustic core material. Because of its design,
it allows a room to
get professional grade
sound quality down
to under 100Hz. No
other system currently
on the market place
can provide this level
of treatment with as
low of a profile. With
a low 1 ¼” profile,
this material allows
our clients to achieve
improved sound quality
performance two entire
octaves lower than
typical fiberglass systems of similar thickness.
One side of the panel is a low-frequency absorber that
also reflects mid- to high-range frequencies and keeps
sound from escaping into other rooms. The other side
absorbs mid- to high- range frequencies. As a result,
CinemaTech’s professional installation team and
acoustician have the ability to fine-tune your home
theater and/or listening room to achieve the highest
acoustical performance available.
ARS Diffusive Panels
These plastic molded panels are specifically designed
to fit seamlessly with the reversible acoustic panels to
provide excellent diffusion. This will “liven-up” a space and improve overall imaging
for the best enjoyment
of the entire acoustic
frequency spectrum.
These diffusers uniformly disperse mid
and high frequency
sound into the room
while enhancing surround sound, stopping
flutter echoes, and/or
redirecting reflections.
The ARS Diffusive Panels consist of a random series
of column stacking diamond shapes. The height varies
while keeping within the 1 ¼” framework of the ARS
system. Because of the rounding of the edges, this diffuser works considerably better than straight edge diffusers,
which often give a snap flutter at the higher frequencies.
Other diffusers on the market are slotted either horizontally or vertically which only gives horizontal or vertical polarization scattering, CinemaTech’s ARS Diffusers
are diamond shaped and give multi dimensional scattering (both horizontal and vertical polarizations). They
have also been tested for ASTM E 84 flame spread of
less than 25 - not available in most alternative diffusers.

Acoustic Room Systems
ARS Fabrics and Retainers
Working together, CinemaTech’s ARS fabric and retainers create a system that covers the acoustic
wall panels and other components (speakers, projector housing, etc..) with a continuous, smooth
surface. These exceptional fabrics are acoustically transparent and will accept any molding, trim or
wall hanging and are easily incorporated into any interior design scheme.
With over 500 patterns and colors, CinemaTech’s ARS fabric gives you the creative freedom to
treat wall surfaces and both angled and curved profiles. Attached at the periphery, the retainers
hold the fabric in place without glue or resins, producing a smooth and finished appearance. The
retainers allow the fabric to be changed as needed and also provide a hidden raceway for low
voltage wiring.

Acoustic Room Systems
Why Acoustics Are Important
What is the largest signal processor in your home theater system?
What is the most integral component in making your system the best it
can be?
If you answered “the room” to both questions above, you have a better
understanding of great sound and acoustics than the average home theater
enthusiast.
The Single Greatest Component
In any home theater system, the room is the single component that will
make or break how the system will sound. In today’s market there are great
speakers, amplifiers and pre-amps to choose from at many different price
levels. With so much great gear to choose from, it’s easy to get caught up
in the electronics and forget the most important component, the theater
itself! Recent data shows that fewer than 10% of all home theaters currently
address room acoustics. There are many reasons why this seems to happen, but the most common is a lack of
understanding by the customer and the dealer.
In this article we will give you information on room acoustics that will assist you in making decisions to
improve your listening environment so that you can receive the peak experience in your home theater. Let’s
begin with the basics of room acoustics.
What does an acoustically correct room sound
like?
Have you ever drive a car that you felt handled well
and seemed to have good pick up and a smooth ride
until you drive a luxury vehicle. When you go back
to your car, you can easily tell the difference. Similarly, most people think their room sounds fine until
they get into a room that has great acoustics. An
acoustically correct room should have proper tonal
balance, precise imaging and impeccable speech
articulation and intelligibility.
Tonal Balance
The easiest way to explain tonal balance is to think
of an orchestra. In an orchestra many instruments
make up the spectrum of sound you hear. The tubas
are in the bass range, the violas and French horns in
the middle, and flutes and piccolos are in the high
range in an acoustically correct room all the
A550-01
Acoustic Room Systems
different frequencies should behave evenly. This is seldom the case. In an
average room usually the biggest problem is the bass, or low frequencies.
Boundary reflections in the low frequency range causes bass to smear become muddy and can cause volume fluctuations. This is most evident in the
corners of the room. Corners are pressure zones that cause bass to resonate,
which makes certain frequencies become louder, while others may get lost
completely. Unwanted reflections in the mid and high frequencies can ruin
tonal balance, speech articulation, and imaging.
Imaging
Imaging is the term we use for where special cues are in a room. This is
extremely important when it comes to two channel listening with music.
When you listen to a good recording you should have an image of where the
instruments and voices are in the room. You should be able to say “I hear the
drums in the back, the vocalist sounds like she is in front of the drums, the
piano is to the left, the guitar is on the right, etc.” If reflections in the room are not properly controlled, this will
not happen.
Another telltale sign of a problem is when a loud speaker becomes too evident in the image. You should not be
hearing the sound coming from the loud speaker. For example, as your favorite actor is walking across the screen,
his voice should be with him, not trailing or coming from any other place. His voice should move smoothly across
the screen, not jump from one speaker to the next. The same goes for surround speakers. A plane flying overhead
should move from front to back, not jump from the front speakers to the rear with nothing in between.
Speech Articulation and Intelligibility
Another serious problem in movie listening is that many people have trouble discerning the voices over the music
or background sounds. This is because they are getting an imbalance between high, mid, and low frequencies in
their system. All too often, the highs have been absorbed with soft material on the walls, carpet, furniture, bookshelves, etc, but the low frequencies are still booming around the room. Often times people put in soft acoustic
panels and use too much absorption in the higher frequencies and end up with an over damped room. Rooms
where too much high frequency control is implemented make you feel as your ears are plugged when you are in
them.
This is also where speech articulation and intelligibility come into play. Speech is made up of low and highpitched sounds, just like music. Vowel sounds are lower in frequency than are consonant sounds. Try for yourself. Say A, E, I, O and U and listen to the pitch of the sound. You should hear a drone tone, a bass sound that is
the same for all vowels and then you hear the midrange, which is different for each vowel. Now say the sounds
that an S, a T, or a K make and you hear the low drone tone plus the midrange vowel sound but then something
new, a hiss type noise in the upper frequencies, the sibilance. If you are listening in a room with heavy carpet,
curtains and large fabric couches, where the higher frequencies have been controlled, but the lower ones have not,
the vowels end up lasting too long. They will begin to overpower the quieter sibilance and that is when people
complain they can’t hear what is being said in a movie. Turning up the volume doesn’t help;
you just get a louder version of what you heard at a normal volume.
A550-02
Acoustic Room Systems
Treatment Methods
It is extremely important that we pay attention
to all the above aspects when treating a room,
and not just absorbing all the upper frequency
ranges. Bass absorption needs to be implemented, usually starting in the corners. This
takes care of many low frequency boundary
reflections. Mid and high frequency absorption is used for reflections that help improve
imaging and speech articulation. Diffusion is
used to help with flutter echo and reverb without making the room sound “over damped” or
too dead. Do not let someone tell you that the
room is ‘acoustically treated ‘because they put
a few fiberglass panels on the wall!
Décor and Design
“I want the theater to look spectacular, “is usually one of the first things we hear from the customer and interior
designer. It is important to know that the acoustician wants exactly what the customer and the designer want, a
great looking room that sounds as good as it looks. The best acoustical systems are just that, engineered systems
that allow the designer to create a look and feel that the homeowner wants, while providing specifically designed
products that create great acoustics without being seen.
It is possible to have great acoustics and beautiful interior design. However, many custom audio video dealers are
hesitant to bring up acoustics for a number of reasons. Some of these reasons may be lack of knowledge, fear of
the designer, or that they feel more comfortable focusing on selling electronics. These are all real concerns, but as
we have stated, they can all be overcome and the balance between design, acoustics and electronics can be struck.
If your dealer has not brought up acoustics, ask them why or look for another dealer. The bottom line is the dealer
is doing a disservice to his customer if he does address acoustics.
When you are planning your theater make sure your dealer uses an acoustics company that specializes in small
room acoustics. Large room acoustics, like corporate facilities, auditoriums, churches and the like are very different and not applicable to a private home theater. Small rooms are very different from large rooms because your
ears are close to the acoustical products that are being used. Every product has its own idiosyncrasies and it is
important to know how they differ in “near field listening” as opposed to what you hear in a large room when you
may be 50 feet away from the acoustical products.
This may all sound overwhelming to the average buyer, but it is no different than looking at the electronics and
wires and connections. Most people would not buy all the electrical components of a very high-end home theater
and try to install it all themselves. The same is true for acoustics. When you make the decision that you are going
to invest in a state of the art theater experience and you want the best, do it right and hire the professionals. They
have the tools and knowledge to make certain that the job is done
correctly so that the listener enjoys a great theater experience.

The Difference Between
Acoustic Treatment and Noise Control
We get asked this question regularly. There is a common
misconception that when we go into a room and treat it with ARS we
are “sound proofing” the room. This is not the case. Sound proofing is
a term not unlike fire proofing. Everything melts or burns at a certain
temperature. The same goes for sound or noise. If it is loud enough
the waves will penetrate just about anything. What people call “sound
proofing” is actually referred to in the industry as “noise control”.
Noise is any unwanted sound that escapes out of your room or leaks
into your room. The best way to achieve the proper amount of noise
control to insure that you will have a pleasant listening experience is
by mechanically de-coupling the wall surfaces from the studs of the
room. This de-coupling reduces the vibration of sound that hits the
wall surface and reduces how much it passes through the wall. We
have several ways of doing this depending on the type of wall and the
desired level of noise control.
Acoustic treatment for the interior of the room has a completely different purpose and it is the most important
aspect of any listening environment. All rooms, especially what we consider small rooms (dimensions under
35ft. in length and width and less than 15ft. high) have acoustical issues that must be addressed in order to
provide the best listening experience. Hard wall surfaces cause reflection and echo problems that must be
dealt with. Also, corners of rooms cause low frequency build up, usually referred to as room modes or room
resonances. This build up has to do with low frequency pressure that behaves like a self propagating wave form.
What the listener in turn hears is a bloom in the bass range that is unpleasant. It can sometimes cause pressure
in the ears at higher volumes. It can also mask higher pitches making speech less articulate. The ARS system
is specifically designed to deal with these problems very efficiently in order to balance the room out. Because
our system works so well in the 100-300 cycle range, which is low frequency, we can do a much better job than
most of our competitors who use a majority of products that only work above 500 cycles. Only about 10% of
the acoustical issues in a room are in that range. About 80% are in the 100-300Hz range.
Our goal is to make a room pleasant and comfortable sounding in order for you to have the best experience
possible in the theater. We do this by looking at the noise level in the room and the signal level in the room and
getting the best possible ratio of signal to noise. We are very careful not to “over damp” the room. This is quite
common in modern day home theaters and it is very unfortunate. If you walk into a room and get the feeling
your ears need to “pop” like on an airplane or the feeling you get when you have a head cold that is the sign of
an over damped room.
With the ARS treatment we tune the room acoustically to maximize the performance of the electronic equipment
supplied by the AV Dealer – comparable to viewing a work of art with proper lighting – if you’ve already made
the investment in the art doesn’t it make sense to spend a little more and see it how the artist intended?
