Noise has documented adverse health effects, however, psychological processes and moderating factors influence the relationship between noise and health outcomes. Research on restorative environments suggests that certain environments provide high quality restorative experiences that may act as moderators of adverse conditions. A questionnaire study was conducted in urban residential areas with road-traffic noise exposure between LAeq, 24h 58 to 68 dB at the most exposed façade. The dwellings had “quiet” indoor section/s and faced a “quiet” outdoor courtyard (LAeq, 24h < 45 dB). The present paper examines the physical environmental quality of the “quiet” courtyards (PEQC) and explores the effect of PEQC on health and well-being. Data were collected from 358 residents (18 to 75 years of age) and four groups were formed based on sound-level categories (58-62 and 63-68 dB) and PEQC classification (low and high). At both sound-level categories, the results indicated that high PEQC-classified “quiet” courtyards provided opportunities for rest and relaxation, which may have moderated the effects of noise with regard to less noise annoyance and noise-disturbed outdoor activities. However, due to high sound levels at the trafficked side of the dwelling, a “quiet” indoor section and a high PEQC-classified “quiet” courtyard could not counterbalance completely the adverse health effects of noise. Thus, 17 and 28 % were still noise annoyed at 58-62 and 63-68 dB, respectively.
