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 opportunities. Data were collected at Rainbow Bridge National Monument during June 2014 to add to the backcountry dataset collected at four National Parks during 2011. Visits to Rainbow Bridge are of shorter length than previously studied and the site is valued for both scenic and cultural/historic aspects, further expanding the dose-response dataset. This report describes the study methods, visitor surveys and data collected at Rainbow Bridge. Dose-response relationships were developed for the complete backcountry dataset inclusive of the 2014 Rainbow Bridge data. The models developed can be used as a tool for evaluating potential effects of air tours on visitors to National Parks.
