    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).

    The neonatal intensive care unit (NICU) context and the perceived soundscape: a grounded theory approach
    (Sage Publications, Inc., 2024-07) Orhan, Cemre; Yılmazer, Semiha
    Background:Studies address excessive sound levels and their adverse effects on infants in neonatal intensive care units (NICUs). However, objective measurements represent merely one aspect of the acoustic environment, and investigations into staff’s perceptions of the acoustic environment remain scarce in the NICU context. A holistic approach, soundscape, is needed to explore the acoustic environment in-depth. Aim:This study aims to (1) contribute to indoor soundscape literature and inform decision-makers of future NICU design and research by focusing on staff members’ perceptions of the soundscape and (2) explore whether there is a relationship between staff members’ perceptions of soundscapes and the built and acoustic environments of one NICU. Methods:Following the ISO/TS 12913-2/3 protocols, semi-structured interviews were conducted with 10 NICU staff members and analyzed using the grounded theory to generate a conceptual framework for NICU soundscapes. Results:The results indicated that the task-related sounds, including false alarms, were neutrally responded to as they evoked acceptance and adaptation behaviors. The sound sources perceived as irrelevant were responded to negatively. NICU staff indicated that although they expect to hear alarms clearly, specific features of alarms caused several physiological and psychological problems. Conclusions:The findings of the study revealed the importance of conducting a soundscape approach to investigate NICU acoustic environment in detail. The study showed that staff members’ perceptions and responses primarily depend on the context rather than on sound levels.
