The Federal Aviation Administration (FAA), with the cooperation of the National Park Service (NPS) and assistance of the U.S. Department of Transportation, John A. Volpe National Transportation Systems Center (Volpe Center) is developing Air Tour Management Plans (ATMP) for all national parks with commercial air tours, with the exception of the Grand Canyon National Park (GCNP), tribal lands within or abutting the GCNP, air tour operations flying over or near the Lake Mead National Recreation Area solely as a transportation route to conduct an air tour over GCNP, Rocky Mountain National Park, and national park units located in Alaska. An important area of technical support is the determination of representative baseline ambient sound levels for the study parks. The FAA, with the assistance of the Volpe Center’s Environmental Measurement and Modeling Division, and the NPS conducted baseline ambient sound level measurements during August 2004 in Glacier National Park. Ten to eighteen days of acoustical and meteorological data were measured at eight sites throughout the park. This document summarizes the results of the noise measurement study.
