<ul><li> 1. Importing Model to Ecotect Anaysis.</li></ul><p> 2. .3ds geometry--Ecotect 3. .3ds geometry--Ecotect 4. Conclusion: Analysis will retard or take long time. 5. Revit and EcotectTag the object carefully in Revit forgbxml filetype! 6. Revit model tagged as shaded part and untagged as un-shaded part.To import gbxml format from revit for analysis, whole part should be completely tagged 7. Conclusion: Analysis will work but cylindrical geometry will be a mess as ecotectconverts it into triangular components. 8. Avoid Complex Geometry as far as possible.Cylinder computed by Ecotect becomes more complex triangular geometry 9. More Simplified geometry for Ecotect ModelCarefully deleted the outer cylindrical from imported xml file andcreated cylinder surface on ecotect so that analysis is done smoothly. 10. Acoustical Analysis 11. Set Sound Source and Reflectors (ceilings) 12. Generate Rays 13. Acoustical AnalysisReflector position and orientation calculation 14. Trial 1Default 15. Trial 112m 16. Trial 1Default12m 17. Trial 1Default12m 18. Trial 1Default12m 19. Conclusion of Trial 1 More REVEB sound was detected. Hence need to modify-Geometry-Orientation (incident angle etc.) Material quality is kept as default. Hence parameters to control in the analysisare Reflectors (ceilings) property. 20. Trial 2Lowering ceilingDecreased by 3m9m 21. Trial 2Lowering ceilingDecreased by 3m9m 22. Decreased by 3mTrial 2Lowering ceiling9m 23. Trial 3Increased by 3m15m 24. Trial 315m 25. Conclusion of Trials 2 and 3 As we change the heights of the ceiling, justabove the stage, quality changes drastically As we lower more noise is observed As we higher the ceiling good quality isobserved for same directed ray generated. 26. Acoustical AnalysisMaterial assignment to the Reflectorsat height of 12m 27. Assigning all reflectors as Acoustical Tile. 28. Table to feed different NRC Values 29. Feeding different Absorptive value for different frequency. 30. Adding Material-NRC.03dia=30m12m 31. Adding Material-NRC.0312mdia=30m 32. Adding Material-NRC.61dia=30m12m 33. Adding Material-NRC.85dia=30m12m 34. Conclusion of different NRC Values For Higher Noise Reduction Coefficients (NRC0.6 and above) most of the sound waves areobserved that leads to Dryness of Soundwhich seems to be bad of an amphitheatre. For lower NRC(0.3) we have variety of soundvariation which is not desired Hence selected NRC 0.56 which is 12 mmMineral Fiber Material which is also fireresistant. 35.
