Abstract:
Results are presented of a small longitudinal study of community response to road traffic noise following an increase in traffic along a residential street. A total of 20 respondents were surveyed and they showed no evidence of adaptation to the increased noise over the period between 7 and 19 months after the increase in traffic. Respondents' assessments of annoyance with the before-change conditions, made retrospectively after the change, were quite different from the assessments of annoyance that they made before the change occurred, though most of this difference was contributed by 8 of the 20 respondents. This small data set, when put together with other evidence on response to changed conditions, suggests that response bias is present in steady state assessments of annoyance and of a magnitude which would significantly affect the validity of self-reports of annoyance.
