This report provides uncorrected noise exposure level data measured using an integrating sound level meter at a single measurement location during the recently completed, week long, FAA helicopter noise test. In addition to the measurements reported, primary acoustical measurements were conducted. This acoustical data (acquired for nine microphones) will be combined with flight path track data processed at the FAA, Dulles Noise Laboratory by D. W. Ford. Meteorological data acquired from surface readings and radiosondes will be processed by U.S. Weather Service personnel.
