Sažetak
Urban parks are areas of nature and leisure which should have a favorable acoustic environment. The quality of this soundscape is not only determined by the equivalent noise level but also by the sounds that visitors walking through the park are likely to notice. To investigate which indicators, derived from physical measurements, could be used as an indicator for the soundscape quality, a study in 8 urban parks within Antwerp, one of the largest urban areas in Belgium, was conducted. The study combined a sound measurement campaign and a survey administered to visitors. Continuous, mobile sound recordings were performed with two to three sound recording devices, carried by researchers performing random walks through the parks. Next to the audio, instantaneous 1/3-octave band levels were logged, as well as instantaneous GPS data, such that the walks could be fully reconstructed afterwards. During the time periods that the measurements were performed, a face-to-face questionnaire survey was conducted among the park visitors, in order to find out their opinion on various acoustical aspects of the parks. In this paper, firstly, results of the measurement campaign are presented in the form of noise maps. Secondly, a range of acoustical indicators is compared to the individual interview responses using regression analysis. One of these indicators is the noticeability of different sounds within the soundscape of each park, calculated using a biologically inspired automated sound recognition model. This validates the methodology for assessing park soundscape quality that is applied in this study.
