Abstract:

Approximately 85 National Park units with commercial air tours will need Air Tour

Management Plans (ATMPs). The objective of an ATMP is to prevent or mitigate

significant adverse impacts to National Park resources. Noise impacts must be

characterized in relation to representative baseline ambient sound levels.

Computing ambient sound levels for acoustic conditions in National Parks is not

straightforward. The National Park Service and Federal Aviation Administration,

both supported by the Volpe Center, are evaluating current methods and developing

standards for computing ambient sound levels in National Parks. This report

describes the results of several on-going analyses: (1) Analysis of ambient data

measured under high-wind conditions; (2) Quantification of the differences between

in situ observer logging versus offline review of digital recordings; and (3)

Computation of natural ambient and existing ambient without air tours.
