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)or Voluntary Agreements (VA) 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, exempt park units (50 or fewer annual tours) 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. For approximately two weeks during the summer (September 2004) and one month during the winter (March 2010), the Volpe Center conducted baseline ambient sound level measurements in Canyon de Chelly National Monument. Acoustical and meteorological data were measured at five sites in the park. This document summarizes the results of the noise measurement study.
