EVALUATION OF DIYARBAKIR GAZI STREET SOUND ENVIRONMENT PERCEPTION BY SOUNDSCAPE APPROACH

Abstract

In this study, it was aimed to measure the perception of sound environment of users in urban spaces with sound quality metrics (loudness, sharpness, roughness, and fluctuation strength). For this purpose, a questionnaire was applied to participants in Gazi Street, Surici district of Diyarbakir, which was selected as a field study. In the questionnaire study, participants were asked about the demographic / personal characteristics, questions about the purpose and duration of use of the space, and 35 adjective pairs with 5 bipolar scales in order to determine the perception of the sound environment. Binaural sound recordings were also performed simultaneously when the survey was conducted. The quantitative data of the loudness, sharpness, roughness, and fluctuation strength metrics of these sound records are calculated. By analyzing the results obtained from the questionnaire and the quantitative data of the sound recordings, correlations between the sound environment perception of the users and the sound quality metrics were determined. Apart from the quantitative data of sound recordings, the effect of the parameters (demographic / personal / social) which can affect the perception of the sound environment in urban spaces has been tried to be determined. In addition, the relationship between quantitative data of sound recordings and meteorological data has also been analyzed.
