The effect of soundscape on the students' perception in the high school environment
(Institute of Noise Control Engineering, 2016) Çankaya, Sıla; Yılmazer, Semiha
In 2014, ISO 12913-1 standard was established for the conceptual soundscape framework to assess soundscape studies. According to this framework, soundscape process includes the examination of acoustic environment and its sound sources, and their influences on the humans' auditory sensation, as to react that, humans' interpretation of auditory sensation, responses and outcomes. Aim of the study is to create this conceptual soundscape framework in high-school environment and to examine the effect of soundscape on the students' perception. The study was conducted in two spaces as classroom and computer laboratory with 30 students in Bilkent High School; Ankara. To understand acoustic environment, in-situ measurements were conducted. Moreover, semi-structure interview results were evaluated to understand the students' perception of soundscape. Generated conceptual framework revealed different relations between students' perception and sound preferences. Students mostly expect to hear speech in classroom whilst computer fan sound in computer laboratory. Moreover, the most positive sound sources are birds singing in classroom whilst laughter in computer laboratory. Speech is found as most negative sound source in both spaces. Students responded these sound sources with positive approaches such as promoting the relaxation, interaction and with negative approaches such as distraction and annoyance. © 2016, German Acoustical Society (DEGA).

Identification of individuals' emotional response to the indoor soundscape in public study areas via semantic differentiation
(Institute of Noise Control Engineering, 2017) Acun, Volkan; Yilmazer, Semiha
Aims of this research is to identify individuals' emotional response to the sound environment of public study areas. The research has taken place in the public study areas of Bilkent University Campus. These study areas are located at the Dormitories, the Fine Arts Buildings, the library, and the Faculty of Science. In order to explore individuals' response to the auditory environment, a questionnaire survey and in-situ measurement of sound levels (LAeq) have been conducted. Questionnaire survey consisted of two main parts. In first part students have identified the sound source, how often they hear each one, and their satisfaction with the sound environment. Second part consisted of twelve seven point semantic differential scales (SD). Semantic scales were chosen in order to identify individuals' emotional response to the soundscape. Questionnaire survey are held with 30 student from each public study area, 120 students in total. The data gathered from the questionnaire survey are analysed using IBM SPSS 21 Statistics Software. Factor analysis was used to identify the perceptual dimensions of soundscape. Three factors were identify as a result of the analysis, which are, well-being, activity/communication and functionality. Even though the ANOVA F-Test found no statistically significant difference between the study areas in terms of satisfaction with the soundscapes, each areas has sound environment characteristics.
