Psychophysiological impacts of traffic noises in urban green spaces.

The goal of this study is to investigate the psychophysiological effects of traffic sounds in urban green spaces. The experiment took into account four traffic sounds: road, ordinary railway, high-speed train, and tram. The results revealed that traffic sounds had a considerable impact on both psychological and physiological responses. In terms of psychological responses, it was found that the peak sound level performed better than the corresponding sound level in assessing the psychological impact of traffic sounds. The noise type and noise level were found to have significant effects on the physiological impacts of traffic noises. The physiological response to high-speed train noise was considerably different from the other three traffic noises. The physiological effects of road traffic noise were discovered to be unrelated to the noise level. In the railway noise groups, however, the change in noise level was observed to cause have an impact on the participants' physiological indicators. [ABSTRACT FROM AUTHOR]
