96 This chapter discusses conclusions that may be drawn about the major hypotheses investigated in the current study. Hypothesis 1: Decibel for decibel, rotary-wing aircraft noise is more annoying than fixedwing aircraft noise.

Conclusions and Discussion 97 measurements nor helicopter-adjusted LFSL measurements were any better at predicting annoyance prevalence rates due to dose. In Las Vegas and Washington, D.C., annoyance was not related to dose as measured by the A-weighted, C-weighted, or the helicopter-adjusted LFSL.

98 Assessing Community Annoyance of Helicopter Noise Hypothesis 5: Annoyance is better predicted by time-integrated proximity to flight tracks than by acoustic measures. Regression analyses showed that proximity to the flight path was as good a predictor of selfreported high annoyance with helicopter noise as helicopter noise levels.
