Evergreen trees and shrubs are particularly suitable for year-round screening. Screening is possible by: Fence, walls, trees, ground level buildings which are not vulnerable to noise distur- bance can be used to screen more sensitive ac- commodation. in this design the outdoor area sound enterance is protected by a higher ground level form and a fence EXIT - - EXIT - - SCULPTURE AREAS AUDITORIUM ENTRY SCULPTURE 2M HIGH ACOUSTIC FENCING AREAS AUDITORIUM ENTRY OUTDOOR SEATINGS FOUNTAIN OUTDOOR SEATINGS FOUNTAIN ENTRY ENTRY translating room grass covering as a 2 translating room control 3 1 surface treatment translating room 4 to control traffic ZONING noise men's 5 back stage 12 ZONING SPACES LIKE MAKING THE GROUND AS BUFFER FOT women's 6 FIRST FLOOR AUDITORIUM AND FACING THE BACK STAGE AND translating room 9 translating room control COMMON AREAS TO THE NOISY 10 7 translating room 11 PARTS TO MAKE TRANSITION SPACES. buffering spaces  ANALYSIS CALCULATION 134 h Seat # 1 : sound path calculation - = ( R1 + R 2 ) - D = (9+ 11)- 12m = 8 meter Convex reflectors : Good for speech and music because the difference used at the stage due to the following reasons CALCLATION FOR HEIGHT OF THE CEILING is between 7 to 10 meter for the front seat Audience size floor area per seat : 0.57 to 0.74 meter Seat # 2 : sound path calculation - - widely spread reflected sounds = ( R1 + R 2 ) - D = (27+ 17)- 41m - Enhances diffusion Recomonded volume / Seat vaues : = 3 meter - Most effective max = 5.1 cubic meter Excellent for speech and music because the difference min = 2.8 cubic meter is below 7 meter for the last seat at 67 degrees Ceiling height = Volume Floor area Ceiling heigh = 5.1 cubic meter = 6.89 meter h 0.74 square meter 25 h Reflection path throughout the room : Balconies slope sound movement under the balcony raising the balconies upward to increase Absorber pannels for eco control at the back under balcony voume used 26 of slope to prevent sound shal- lows under the balconies plant Schedule Girar Wild Dagga Aloe Vera 10 - 15 meters
