CONDITIONS FOR GOOD ACOUSTICS IN AUDITORIUM

AVOIDANCE OF STRONG ECHOES AND FOCUSING OF SOUND RAYS

•Strong echoes and focusing lead to a non uniform sound level within the room which is not desirable.•These features of the auditorium design : scatters, convex (non-focusing) ,surfaces on balcony fronts, absorption materials, carpet .INTIMACY, CLARITY

•Intimacy implies a short time between the first reflection of sound to the ear and the direct sound from the source.•Sound level of the source needs to be distinctly higher than the background sound. This promotes good speech intelligibility.

REDUCTION OF SOUNDS AND VIBRATIONSCONDITIONS

•This keeps the background noise level down.•Thick heavy walls and doors help to reduce the background noise.•Seals on doors are important .•It is also important to reduce noise from air handling systems, walking on floors and also talking outside the room.

FOR ACOUSTIC INSULATION THEY MAINLY USED WOOD.

WOOD ON OUTSIDE, PLASTIC COVER INSIDE TO PREVENT FROM LEAKAGE AND COIR AT LAST.

ACOUSTICAL INSULATION

FLOORS AND CATWALKSAUDITORIUM•The material used in the flooring is woolen carpet.•These woolen carpets are very good absorptive material.•The carpet is 80% wool and 20% nylon.

STAGE•The stage floor is made of hard wood.

CATWALK•There are 33 Back drops which work on counter balance system.•The steel beams in the catwalk are coated with vermicular coating, hence heat can be absorbed for 5-6 hours.•There is a catwalk above the seating area for changing and repairing lights. The intensity of lights can be controlled from the technical control room.

1.Generally used to absorb sound in order to avoid echo effect.

2.The width of wood wool fibres varies from 1.5 to 20mm, while their length is usually around 500mm.

3. SPEAKERS WERE PROVIDED AT THE SIDES ON LOWER SIDE AND FOR THE BALCONY PEOPLE AT THE TOP.

WOOD WOOL MAT AND FABRIC

1.BLOCKS ARE MADE IN WIDTH NORMALLY UPTO 3 AND HALF INCH AND IN LENGTHS FROM 6 INCH TO 15 INCH ..BUT LENGTHS OF 9 -12 INCH ARE MOST COMMON.

2.THICKNESS VARY FROM 1 -1.5 INCH .

3.SURFACE IS COATED WITH BLACK VARNISH JUST BEFORE LAYING .

4.IF FINE FINISH IS REQUIRED THE SURFACE SHOULD BE SEALED AND WAXED.

5.IF THE WOOD IS OF OPEN GRAIN SUCH AS OAK, IT SHOULD BE TREATED WITH WOOD PASTE FILLER PREVIOUS TO WAXING.

OTHER FACILITIES:

THE GREENARY TO PROVIDE A GREEN AND ENVIRONMENTAL FRIENDLY ATMOSPHERE AROUND THE

NIGAMAGAMAM COMPLEX INCLUDING THE PARKING AREA, A BEAUTIFULLY DESIGNED VAST LANDSCAPE GARDEN HAS BEEN ESTABLISHED.

THE GARDEN CONSISTS OF SOFTFARE AND HARDWARE COMPONENTS. THE SOFTWARE COMPONENTS INCLUDE VAST STRETCHES OF CARPRT GRASS –

BERMUDA AND CORREAN GLASSLANDS –SEASONAL AND PERENNIAL PLANTS, SHRUBS, CREEPERS, GROUND COVER, A ROSE GARDEN, SMALL ROCKERY, POTTED PLANTS AND PLANTERS.

THE HARDWARE COMPONENTS CONSISTS OF SEVERAL FOUNTAINS INCLUDING A STEP FOUNTAIN.

A TOTAL OF 75 VARIETIES OF PLANTS AND TREES MAKEUP THE GREENERY OF THE NIGAMAGAMAM

WATERING OF THE GARDEN AREA IS DONE BY THE MMODERN METHODS OF EITHER DRIP OR SPRINKLE TYPES.

THE GREENERYThe green zone acts as a sound barrier for preventing noise indoors.

Our OBSERVATIONs

BECAUSE OF THREE REASONS THE AUDITORIUM IS CONSIDERED AS NOT A GOOD ONE

1.ALL EXTERIOR WALL ARE JAALI WALLS .ONLY FEW WALLS ARE COVERED WITH GLASS.(due to which exterior noise transmits into the inside of auditorium).

2.The roof pattern is not acousticaly treated with proper insulation.

3. There are many reflections and echoes being produce inside the auditoium when speeches are going on.
