    Analysis and evaluation of soundscapes in urban public squares through questionnaires and sound quality metrics
    (The Institute of Noise Control Engineering of the USA, Inc., 2015) Bahali S.; Tamer-Bayazit N.; Aydin D.Ç.
    Soundscape studies have long been focused on the importance of the semantic properties of sound along with its physical characteristics. As a continuation of the previous study about the soundscape perception of four squares along Taksim and its two kilometer long route to Tunel, this paper investigates the sonic environments through comparisons between subjective parameters and psychoacoustic parameters such as equivalent sound pressure levels (Leq), loudness (N), roughness (R) and sharpness (S). The analysis and evaluation of soundscapes were examined for the route overall and four key squares. At each location questionnaries were completed and binaural recordings were conducted in addition to questionnaires. Sound metric analysis were accomplished through post-signal analysis methods in both cases. It was aimed to obtain if dissimilarities between perceptual properties of four key squares can be observed via sound metrics. © 2015 by ASME.

    Sustainable soundscape: A field study in the historical Suriçi area of Diyarbakir
    (The Institute of Noise Control Engineering of the USA, Inc., 2015) Aydin D.Ç.; Uysal E.; Akça Y.B.Ö.
    Various studies have been carried out regarding perceptions of sounds capes in cities or large public spaces. Most sounds cape studies outline the considerable importance of the informational properties of sound, along with its physical characteristics. This study was conducted to investigate the sounds cape preferences of the sonic environment of the historical Suriçi area of Diyarbakir. The Suriçi area has been at the center of many civilizations and cultures over thousands of years. This area includes a number of noisy activities including traditional craft operations such as coppersmiths, blacksmiths and stove manufacturers. Soundscape methodology and analysis techniques have been used in this study to determine the effects of the soundmarks associated with these traditional craft manufacturers. Binaural recordings were conducted in addition to questionnaires. Participants who were questioned were residents of the city. The results imply that, despite the high sound pressure levels, residents responded positively to these sound marks. From these results it can be stated that the special sound marks of a city must be acknowledged as part of the cultural heritage functioning in a sustainable living environment. © 2015 by ASME.
