Abstract [sv]

Guideline values for traffic-noise exposure in urban outdoor spaces are missing, mainly due to the lack of knowledge on the effect of noise on perceived soundscape quality. For this reason, a questionnaire study was conducted in 16 city parks and green open spaces in Stockholm. In total, 1116 respondents answered questions on, inter alia, perceived soundscape quality and road traffic noise annoyance. The areas included a wide range of soundscapes, from highly traffic noise exposed city parks to quiet suburban open spaces. Consistent relationships were found between, on the one hand, measured overall sound levels and, on the other hand, perceived soundscape quality and road traffic noise annoyance. As expected, soundscape quality was negatively related to presence of technological sounds (e.g., road traffic noise) and positively related to presence of nature sounds. These relationships remained also after controlling for overall measured sound level. Taken together, the results suggest, as a rule of thumb, that good soundscape quality in urban open spaces would require day time traffic noise exposure below 50 dBA (Lday). In situations with exposures between 50 and 55 dBA, soundscape design that promotes positive sounds from nature may be efficient in improving soundscape. At higher levels, soundscape design has to be complemented with traditional noise abatement methods in order to achieve good soundscape quality.
