INTRODUCTION | Acoustical Survey
4. Before sound systems existed, the large
grand Cinemas of the past were modelled on
Opera houses with an orchestra pit in front
of the screen which was later replaced by an
organ that came up through the floor.
Traditionally a movie theater, like
a stage theater, consists of a
single auditorium with rows of
comfortable padded seats, as well
as a foyer area containing a box
office for buying tickets.
Movie theaters also often have a counter
and/or self-service facilities for buying
snacks and drinks in the movie theatre
lobby, film posters, arcade games, movie
schedules, theater entrances, entrance
halls, entrance signs, and washrooms.

5. WALL FITTED CARPET
CAN BE A SUPPLEMENT
OR A LOW-COST
ALTERNATIVE TO THE
ACOUSTIC WALL
TREATMENT SYSTEM.
APART FROM ITS
PROTECTIVE FUNCTION,
WALL FITTED CARPET
ALSO WORKS AS
ACOUSTIC ABSORBER.
IT HAS A HIGH
COEFFICIENT OF
ABSORBING SOUND
WAVES, REDUCING THE
REVERBERATION TIME
OF THE ROOM.
THE WALL FITTED
CARPET CAN BE
MOUNTED TO WALLS OF
ALL TYPES OF
CONSTRUCTION, OF
BOTH STRAIGHT AND
CURVED SURFACE. IT IS
FITTED WITH SPECIAL
GLUE.
ACOUSTIC WALL TREATMENT SYSTEMS
CASE STUDY
6. WOOL CINEMA WALL FABRICS
• Cinema uses wool that is heavy- weight,
opaque and extremely durable, in order
to
• Assemble the very best stage drapes,
acoustic sound control curtain systems,
and other
• Wall curtains.
ACOUSTIC PANELS
•Acoustic wall panels are a cost
effective and attractive means of
providing your venue
•With the highest quality audio
performance.
ACOUSTIC STRETCH FABRIC
WALL
•Covering cinema walls with
acoustic stretch fabric is an
alternative to the use of acoustic
•Curtains to manage the sound
and echo characteristics in the
cinema auditorium.
CUSTOM WALL FINISHES
•Specialty cinema can be design
and install any sort of custom wall
finish to give your cinema
•A state of the art appearance.
7. SUSPENDED
ACOUSTIC
CEILINGS
Suspended acoustic ceilings are of vital
importance when building the interior
acoustic environment.
Their main task is to improve acoustic
comfort through sound absorption and
strengthening acoustic insulation of a
particular room.
Acoustic function - high coefficient of sound
absorption and acoustic insulation
8. Manufactured using optimum quality terracotta, these tiles offers
resistance to humidity, heat and superior acoustical performance.
Available in various shapes and sizes, these are readily used in
offices, multiplexes, recording studios and construction industry.
Subtex Ebony, subtex pebble, subtex plane and subtex nubby walls
and ceilings.
These products are widely used for furnishing offices, auditorium,
retail outlets, Multiplex.
Its range is appreciated for its humidity tolerance, durability and
easy access to the plenum.
9. OBSERVATIONS
FLOORING
AND
SEATING
The shape of the cinema theatre
resembles a trapezium so that no two
adjacent walls are perpendicular.
This is done so as to avoid corner
echo.
Along with this, parallel walls are
avoided to prevent flutter echo.
10. FLOORING
• FARRAT ISOMAT ACOUSTIC FLOATING
FLOORS are used to provide very high
isolation between noisy or quiet
rooms and surroundings rooms.
• They can be built as box in box
systems with the walls and ceiling
build off the floating floor.
TYPES OF
FURNITURE
USED IN
MULTIPLEX
THEATRE
• Theater seats come in a variety of
widths, depending on the age of the
theater, the space available and the
target audience.
• High end theater may have luxury
seating that is wider than the cushions
at your local multiplex.
• Movie theaters may also differ from
live theater spaces in seat width.
• Standard seat width varies between
18 and 22”,but older theaters, such as
historic movie houses from the 1940s
and earlier, may have 15 -16” seat.
11. The principles used in the seating of a
movie theatre are mostly derived
from the conventional
amphitheatres.
For example – the tiers of seats, the
jagged arrangement of seats so that
no two seats are exactly behind one
another, maintaining the proper level
difference in the consecutive rows to
ensure proper visibility, etc.
