• Abstract:
  The United States Postal Service (USPS) is finishing a two-year demonstration project ; examining the feasibility of mail delivery via hovercraft to remote Alaskan villages. Prior to this ; demonstration project, and in support of the Environmental Assessment (EA) for the project1, the ; Volpe Center Acoustics Facility (VCAF) conducted a “Noise Characterization Study”2 of the ; AP.1-88, the proposed hovercraft for the project. This study took place in Anchorage, Alaska. ; Early in the demonstration project, the Hovercraft Resolution Committee (HRC), a task force ; made up of representatives from the villages neighboring Bethel, Alaska, as well as local and ; federal resource agencies, was made aware of public concern regarding hovercraft noise in the ; remote villages. As a result, sound level monitoring was undertaken during September 1997 in ; order to: (1) study hovercraft noise in the village environment to confirm the applicability of the ; data in the Noise Characterization Study; (2) study village ambient sound levels to determine the ; reasonableness of the 40 dB value assumed in the EA; and (3) compare in-situ hovercraft sound ; levels with those of other village noise sources. The results of this monitoring program are ; presented in Reference 3.3
