• Abstract:
  The National Aeronautics and Space Administration (NASA), Langley Research Center (LaRC), sponsored the Acoustics Facility at the United States Department of Transportation's John A. Volpe National Transportation Systems Center (Volpe Center) and the Massachusetts Institute of Technology (MIT) to conduct a noise measurement study at Logan International Airport in Boston, MA, during the summer of 1999 to examine the applicability of currently available mathematical models of lateral attenuation. Analysis of the data collected revealed that lateral attentuation is a function of aircraft geometry. lateral attenuation for aircraft with tail-mounted engines was found to agree with the published literature, as well as that included in existing aircraft noise models. lateral attenuation for aircraft with wing-mounted engines was found to be less than documented in the literature. This lower lateral attenuation for aircraft with wing-mounted engines results in a general under-prediction of side-line noise in the existing noise models.
