LABORATORY STUDY OF ANNOYANCE TO COMBINED AIRPLANE AND ROAD-TRAFFIC NOISE

摘要

A laboratory study was conducted in which subjects judged the annoyance of sessions of noise which consisted of both separate and combined airplane and road-traffic noises. The subjects judged each session as to how annoyed they were in the simulated living-room laboratory environment and as to how annoyed they would be if they heard the noise in their home during day, evening, and night periods.nThe airplane noises, for equal-session Leq levels (where Leq represents the equivalent continuous sound level), were judged significantly more annoying than the road-traffic nurses for the separate sessions. For the combined sessions, an interaction was found between the airplane-noise and traffic-noise levels which was not adequately assessed by the total energy concept of Leq. Significant differences were found between the projected home responses for the day, evening, and night periods.
