Abstract [en]

Annoyance research typically focuses on single sources and on adverse effects of noise. In contrast, soundscape research focuses on the total sound environment, including all its positive and negative aspects. A major challenge in soundscape research is to develop methods for measuring the perceived soundscape. In the research program “Soundscape Support to Health”, we have developed new methods for this purpose, including listening tests in the laboratory, listening walks in the field and questionnaire studies targeted on the soundscape. We have thus identified major perpetual dimensions of soundscapes (pleasantness and eventfulness), linked these features to important acoustical and informational properties of soundscapes (type of sources), and explored the effect of noise mitigation on soundscape perception. Our research show (a) that pleasantness of soundscapes is related to the presence of natural sounds, whereas eventfulness is related to the presence of sounds from humans, (b) that traffic noise should be reduced to below 50 dBA, in order to have a chance to create good outdoor soundscapes in urban residential and recreational areas, and (c) that mitigation efficiency in sound level of various barriers and facades may overestimate corresponding perceptual mitigation efficiency. Based on these findings, new tools for ‘green labelling’ of soundscapes are being developed.
