Aprašymas
This document summarizes the findings of a study that considers all known aircraft noise dose and visitor response data previously collected in the National Parks. These data consist of almost 2500 visitor interviews and simultaneous acoustical measurements collected at four different National Parks between 1992 and 1999. These data are used to develop relationships that relate the noise (dose) data to visitor response for assessing aircraft noise in the National Parks.
