Initial study of the immediate annoyance of aircraft noise as a function of time of day

摘要

The development of several operational definitions for the relative annoyance of noise intrusions at different times of day was studied to apply these definitions to a real time survey of aircraft noise intrusions in people's homes. The conclusions include: (1) Assessment of annoyance due to aircraft noise exposure can be accomplished by immediate measurement of annoyance produced by individual aircraft noise intrusions in real time. (2) Differences between morning and afternoon periods are statistically insignificant. Differences between evening and nighttime periods and other times of day were small and of little practical significance. (3) The observed ddfferences in annoyance at different times of day do not support the current 10 db nighttime penalty for aircraft noise exposure.
