Abstract:The Federal Aviation Administration and National Park Service conducted joint research to better understand the effects of noise due to commercial air tour operations over units of the National Park System. To evaluate the relationship between aircraft noise exposure and the quality of National Park visitor experience, research was conducted at backcountry sites providing day- and overnight-hiking and camping opportunities. This research expands upon work performed during the 1990’s at frontcountry sites. Over 4600 visitor surveys and fifty days of acoustical measurements were collected and analyzed to develop dose-response relationships for backcountry visitors. This report, the first of two volumes, describes the study methods, visitor surveys, research locations and data collected. Volume two describes the model-fitting approach used to identify the noise exposure metrics and mediator variables that best predict visitor responses to aircraft noise. The models developed can be used as a tool to evaluate potential effects of air tours on visitors to National Parks.
