Environmental noise modeling: A case study near the busiest airport in the world

This case study examines modeling and measurements taken at a project site in Atlanta, Georgia. The site is an expansion of a movie studio to encompass 18 new large sound stages, 8 fixed stages, and support spaces. The site is located just inside the Atlanta I-285 perimeter and directly under a major flight path from Hartsfield Jackson Atlanta International Airport. The studio includes 8 existing sound stages located 3 miles from the expansion. Both long term and short term measurements were take and used to confirm the environmental noise modeling. Modeling was used to predict the impacts on the site and inform the building shell design. At late stages of the project, the Department of Transportation purchased land adjacent to the site and planned to regrade and move a major exit ramp closer to the site. This case study will review the multiple challenges of the project and the environmental noise modeling performed. The project is on-going and not in construction.
