- 3. STAGE The rectangular stage has proper curtains and fins. Its size is 15m X 9m . Everything is electronically controlled. The stage has fixture to hold focus lights, backdrops, etc. Floor: timber flooring. COFFICIENT – 0.1 STAGE FLOORING THE STAGE USES SEGWAN FLOORING TO REDUCE THE NOISE TRANSMISSION TO TOLERABLE LEVELS. AN ACOUSTIC LAYER IS USUALLY LAID UNDER THE TIMBER VENEER FLOORING TO ABSORB THE SOUND WAVES TO A CERTAIN DEGRES. THE LAYER REDUCES VIBERATION OF LOWER SOUND FREQUENCIESTO PREVENT THE VIBERATION OF SLABES AND WALLS BY LOWER SOUND FREQUENCIES.
- 4. CARPET FLOORING THERE ARE TWO TYPES OF NOISE THAT ARE RELEVANT: THE FIRST IS THE HIHER FREQUENCY NOISE COMING FROM MUSIC, SINGING, SPEECH. THE SCEOND TYPE OF NOISE ARE LIGHTER, LOWER FREQUENCY NOISES SUCH AS FOOTSTEPS OF PEOPLE WALKING AROUND. THICK CARPETED FLOORING CONTRIBUTES TO SOUND ABSORPTION. CARPET IS AN OUTSTANDING SOUND ABSORBER WHICH SERVES AS AN ACOUSTICAL AID, AS WELL AS FLOOR COVER. CARPET ABSORBS AIRBORNE NOISE AS EFFICIENTLY AS OTHER SPECIALIESD ACOUSTICAL MATERIAL.
- 5. WALL PANEL THE MATERIAL USED IN THE WALLS ARE WOODEN PANELS, GLASS WOOL. THE GLASS WOOL SHEET APPLIES ON THE WALL BY ADHESIVE AND ON THAT WOODEN BOARDS ARE APPLIED SO THAT MORE AND MORE SOUND ABSORBS. THEY ARE WATER AND FIRE RESISTANT. GOOD INSULATING MATERIAL. POP CEILING THE AUDITORIUM CEILING IS ANOTHER IMPORTANT FACTOR AFFECTING SOUND INSULATION. CEILING PANELS ARE MADE UP OF POP BOARDS. THERE SURFACE HELPS IN SOUND ABSORBTION THEY ALSO PROVIDE FOR ACOUSTICAL INTIMACY, ATMOSPHERE, AND STRENGHENS THE OVERALL SOUND QUALITY. SUSPENDED FROM THE CEILING TO PROVIDE SHORT DELAYED. THEY ARE NOT COMBUSTIBLE
- 6. SEATING THE TOTAL SEATING OF THE THEATRE IS 1100. THE THEATRE IS RECTANGULAR IN SHAPE. THE SITTING IS DIVIDED INTO TWO SEGMENTS AND TWO LEVELS: STALL-850 BALCONY-250 THE CUSHIONED CHAIRS WITH COMFORT ALSO HAVE GOOD SOUND ABSORBENT, WHICH HELPS THE OVERALL REVERBERATION TIME IN THE AUDITORIUM. ADDITIONAL SOUND CONTROL IS ALSO PRESENT IN THE FOAM OF PEDED SEATS. IT ACHIEVE THE SIMILAR QUALITY OF SOUND WHETHER THE AUDITORIUM IS FILLED OR NOT.
- 7. SOUND REFLECTION In order to make the use of sound more efficient, it is necessary for the sound to be reflected back towards the audience. However. the amount of sound reflected, with the added design of these reflections, must be carefully controlled to minimize the creation of echoes. DIRECT SOUND REFLECTED SOUND
- 8. SOUND REFLECTION Ceiling reflectors serve to reflect sound effectively back to the audience. Therefore, the rest of the auditorium must be covered with sound absorbent materials to minimize the resultant reflected sound, making it almost indiscernible. REFLECTED SOUND DIRECT SOUND
- 9. REVERBERATION TIME In acoustics, reverberation is the persistence of sound after a sound is produced. Based on the materials identified on site and the measurements obtained from the drawings, we were able to calculate the absorption of each surface and determine the total room absorption of the auditorium. CALCULATED REVERBERATION TIME RT = 0.16V AT where: RT = reverberation time (sec) V= volume of the room (cu.m) AT = total absorption of room surfaces (sq.m )
