The document discusses various acoustic panel materials and their properties that can be used to improve acoustics in auditoriums. It describes acoustic panels made of sound absorbing cotton and aluminum frames that provide wide frequency sound absorption. It also mentions decorative acoustic wall panels that have both acoustic and decorative functions. Acoustic tiles, drywall, carpet, foam and eco-friendly absorption materials are outlined with their acoustic properties and applications in rooms where optimal sound is desired such as recording studios, theaters and meeting halls. Seating for auditoriums is also covered, describing molded foam, finishes and numbered/identified seats for ease of use.

ACOUSTICS AUDITORIUM SUBMITTED BY LAKSHMI ANIL ANUSHA L ABHILASH K R
GOOD ACOUSTICS INVOLVE • GOOD DISTRIBUTION OF SOUND TO ALL THE SEATS, WHICH DEPENDS ON PROPER SHAPING AND FINISHES OF ALL INTERIOR SUFACES. • NATURAL SOUND DIFFUSION AND ENVELOPMENT. • A SENSE OF INTIMACY FOR THE AUDIENCE AND A SENSE OF ENSEMBLE FOR BOTH PERFORMERS AND AUDIENCE. • PROPER REVERBERATION TIMES THROUGH OUT ALL FREQUENCIES, WHICH DEPEND ON ROOM’S VOLUMEAND THE TOTAL SOUND ABSORPTION OF ALL MATERIALS. • FREEDOM FOR THE ACOUSTICAL FAULTS OF ECHOES, FLUTTER, AND FOCUS.
ACOUSTIC PANEL MATERIAL DETAIL : 1. WIDE SOUND ABSORPTION SPECTRUM 2. HIGH ABSORPTION COEFFICIENT 3. DUST-FREE 4. ASTM E-84 CLASS A STRUCTURE: FILLED WITH NON-COMBUSTIBLE AND MICRO-PERFORATED TREATED SPECIAL SOUND ABSORBING COTTON INSIDE THE ALUMINUM FRAME, AND COVERED WITH THE FIREPROOF FABRIC OUTSIDE. FEATURE: 1. WIDE FREQUENCY SOUND ABSORPTION, GOOD SOUND ABSORPTION EFFECT FOR LOW, MEDIUM AND HIGH FREQUENCY SOUND, THE ACOUSTIC PROPERTIES ARE TESTED BY THE DOMESTIC AUTHORITIES, SHOWN AS BELOW 2. FIREPROOF, DUST FREE, NO FORMALDEHYDE POLLUTION 3. STRONGLY DECORATIVE, MULTIPLE COLORS AND PATTERNS DECORATIVE FABRIC FOR CHOOSE APPLICATION: USED IN THE PLACES NEEDING ACOUSTIC DESIGN: HOTEL, OFFICE, CINEMA, THEATER, CONCERT HALL, GYMNASIUM, RECORDING ROOM, STUDIO, CONFERENCE HALL, EXCHANGE, BUSINESS HALL, KARAOKE HALL, BALL ROOM, HOSPITAL, LIBRARY, STATION WAITING ROOM, RESTAURANT, AUDITION ROOM, HOME THEATER, ETC.

ACOUSTIC PANEL
DECORATIVE ACOUSTIC WALL PANEL MATERIAL DETAIL : 1. any design, any picture can be applied to the panel 2. have both function, acoustic and decoration function Structure: filled with fiberglass inside, aluminum frame, wrapped by fiberglass cloth, and covered with the printed fabric on the surface. Feature: have both functions, acoustic function and decoration function Application: hotel, office, cinema, theater, concert hall, gymnasium, recording room, studio, conference hall, exchange, business hall, karaoke hall, ball room, hospital, library, station waiting room, restaurant, audition room, home theater, etc. Specification: Thickness: 25mm Standard size: 1200x600mm, 600x600mm The biggest size: 6m*1.6m.
DECORATIVE ACOUSTIC WALL PANEL
ACCOUSTICAL TILES Acoustical ceiling tiles • Widely used as a material usually made of mineral or cellular fibers. Sold in panels ranging from 12” x 12” up to 24” x 48”. ACCOUSTICAL DRYWALL • Usually made of synthetic materials, but also made from wool,cotton or other fibers. • Absorptivity is good only in high frequencies, and is based on the thickness. Carpet absorbs sound, but can also attenuate impact sounds since it prevents hard contact with floor surface. NRC ranges typically between 0.20 to 0.55. • Made by proprietary companies, (such as Serious Materials), these panels are made of conventional gypsum and additional sound-absorbing materials. Fairly expensive, approx. $40.00 per 4’x8’ sheet. CARPET
ACOUSTIC FOAM ACOUSTIC FOAM IS AN OPEN CELLED FOAM USED FOR ACOUSTIC TREATMENT. IT ATTENUATES AIRBORNE SOUND WAVES BY INCREASING AIR RESISTANCE, THUS REDUCING THE AMPLITUDE OF THE WAVES. STRUCTURE: PIECES OF FOAM, OFTEN IN THE SHAPE OF CONES OR TRIANGLES ON WALLS, CEILING AND FLOORS. FEATURES: ACOUSTIC FOAM IS A LIGHTWEIGHT MATERIAL MADE FROM POLYURETHANE FOAM EITHER POLYETHER OR POLYESTER, AND ALSO EXTRUDED MELAMINE FOAM. Applications: ACOUSTIC FOAM IS PRIMARILY USED IN RECORDING STUDIOS TO MINIMIZE SOUND ECHOES. HOWEVER, IT CAN PERFORM THE SAME FUNCTION IN HOME THEATERS, MANUFACTURING FACILITIES, EQUIPMENT WAREHOUSES, HOME OFFICES, GYMNASIUMS AND AUDITORIUMS. IT CAN BE PLACED IN ANY ROOM WHERE AN OPTIMAL SOUND MIX IS DESIRED. SPECIFICATION: SIZE: 6' X 3' X 2" (SIX FEET X 3 FEET X 2 INCH) OVERALL NRC: 0.67
ACOUSTIC FOAM
ECO-C-TEX ABSORPTION MATERIAL THE GREENEST ACOUSTIC MATERIAL IN TODAY'S MARKETPLACE . COMPOSED OF A BLEND OF RECYCLED COTTON AND CELLULOSE FIBERS (THE MAJORITY OF WHICH IS POST-CONSUMER RECYCLED NEWSPAPER!) . STRUCTURE: ECO-C-TEX IS A BLEND OF RECYCLED COTTON AND CELLULOSE FIBERS. FEATURES: • HIGHEST QUALITY DIGITAL FABRIC PRINT. • EASY TO HANDLE, INSTALL AND CLEAN. • NFPA FIRE RATED. APPLICATIONS: ACOUSTICAL BAFFLES, OR SOUND BAFFLES, ARE YOUR SOLUTION TO REDUCE ECHO AND HELP CONTROL UNWANTED NOISE IN CHURCHES, GYMNASIUMS, WORKOUT ROOMS, CONFERENCE HALLS, OFFICE SPACES AND OTHER LARGE AREAS WITH HIGH CEILINGS. THEY ARE FUNCTIONAL AND MAKE AN IMPRESSIVE VISUAL STATEMENT. SPECIFICATION: AVAILABLE IN 2MM, 3.2MM AND 6.4MM THICKNESSES.
