| 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 |
