Short-Term Annoyance Due to Night-Time Road, Railway, and Air Traffic Noise: Role of the Noise Source, the Acoustical Metric, and Non-Acoustical Factors

Field studies on traffic noise-induced annoyance have predominantly used estimated outside noise levels. We intended to complement existing knowledge with exposure–response relationships that are based precise indoor measurements. Acoustic recordings inside the bedrooms of nightly road and ratings in following morning were obtained from 40 suburban residents (mean age 29.1 years ± 11.7; 26 females). derived functions for probability be “annoyed at least a little” (%LA). Further analyses compared data current study those two earlier railway aircraft noise. Annoyance increased number events equivalent sound pressure level. The inclusion non-acoustical factors (such as assessment transport) improved prediction considerably. When comparing different sources, %LA was higher than air given LAeq,night, but events. Acoustical well impact short-term induced by road, railway, traffic. varies across which may due differences acoustical characteristics or temporal distribution throughout night.
