A Method for Assessing Turbine Engine Run-Up Noise Impact on Airport Neighbors 780522

A methodology for assessing ground run-up noise exposure/impact resulting from turbine engine performance testing on outdoor facilities was developed. The overall methodology consists of three calculation procedures using dBA levels (measured or estimated) to predict the Day-Night Level (LDN) at any location across existing terrain. The methodology provides the analysis capability required to 1) study noise suppressor requirements in order to minimize costs, 2) locate run-up and test-cell pads, and 3) study the impact of run-up operations changes. It also provides a potential capability for assessing noise exposure from 1) takeoff power check run-ups, or 2) other (non-turbine) static noise sources.
