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).

Modeling and simulation of the ferroelectric based micro gyroscope: FEM analysis
(Taylor and Francis, 2013-09-23) Ozer, Z.; Mamedov, Amirullah M.; Özbay, Ekmel
This paper presents the design and modeling of micro-electromechanical systems (MEMS) on the ternary ferroelectric compounds (PZT) based by using finite element model (FEM) simulation. The conceptual framework establishes five steps to perform the critical analysis: design a novel structure, define the failure mechanisms under the given conditions, analyze different vibrations, analyze the operation principle, and detect resonance modes. In addition, MEMS failure modes were analyzed under different scenarios and the obtained results discussed. Copyright © Taylor & Francis Group, LLC.

Perceived auditory environment in historic spaces of anatolian culture : a case study on Hacı Bayram mosque
(International Institute of Acoustics and Vibrations, 2016) Acun V.; Yilmazer, Semiha; Taherzadeh, P.
This article reports the initial finds of a research that is concerned with the perceived auditory environment within an historical mosque and its surroundings. Haci Bayram Mosque and its surrounding area of Hamamönü has been selected as the research site due to being the historical center of Ankara. Although there are studies concerned with the acoustical characteristics of mosques, there isn't enough research focusing on users' expectation and interpretation of the perceived auditory environment within a mosque. This study adopts the user focused of Grounded Theory to capture individuals' auditory sensation and interpretation of the perceived auditory environment within a historical mosque and its surroundings. In depth interviews are held with the congregation of the mosque and with the individuals sitting around the surrounding area. Based on their subjective responses, a theoretical framework is generated to gain an insight on the factors that affect individuals understanding and expectation from mosques. Acoustical characteristics of the mosque are analyzed by computer simulation and in-situ measurements of sound pressure levels. Objective room-acoustic indicators consist of reverberation time (RT) and speech transmission index (STI). The conceptual framework generated through Grounded Theory shows how perceived auditory environment may influence individuals' response to the physical environment of the mosque by showing the associations between the soundscape elements, spatial function and sense of place.
