Acoustic Design Guidelines for Adults With Intellectual Disability
(European Acoustics Association EAA, 2014) Şaher, Konca; Nijs, Lau; Hordijk, Truus
This paper concentrates on the acoustic design aspects of the living rooms in institutions for adults with intellectually disability. In the living rooms for adults with ID there is even a higher stress on the acoustics since they are more dependent on the acoustical environment compared to normal population. Moreover prevalence of hearing impairment among adults with ID is around 30% and in most cases it is not even recognised. Therefore the rooms for adults with ID need to be designed by taking into account the requirements of the hearing impaired. They need more favourable room acoustics to improve their communication and participation. This paper investigates three main themes: 1) Investigation of impact of building design tools on acoustical quality parameters and determination of most appropriate acoustical quality indicator that translates best into architectural practice for living rooms for adults with ID. 2) Investigation of the relation between user satisfaction and absorption amount in rooms for adults with ID by listening tests prepared from auralizations. 3) Development of architectural/acoustical design guidelines to provide optimal absorption amount for living rooms for adults with ID.

Collaborative Design of an Active Learning Classroom With High School Students and Teachers
(EMERALD GROUP PUBLISHING LTD, 2020) Kepez, Orçun; Ust, Selin
Purpose - The aim of this study is to understand classroom settings desired by high school students and teachers in an active learning classroom. The research question is whether students and teachers will differ from each other when designing an active learning classroom. Design/methodology/approach - In an effort to design a learning environment for an advanced placement programme, action research methodology was followed by conducting a participatory workshop in a real active learning classroom with future users. Working in isolation from one another, students and teachers designed their own classrooms by forming different learning centres. During the study, two groups, made up of ten high school students and seven teachers, respectively, were asked to arrange the furniture in an active learning classroom. The groups were free to form as many furniture arrangement configurations as they wished and were asked to write about their workshop experiences afterwards. Once they had completed both tasks, their plan layouts were examined. Findings - All of the plan layouts were found to fall into one of three categories: a traditional layout, a small group layout or a single large group layout. The written texts were also analysed, which revealed different perspectives of each participating group. As students and teachers explore different learning opportunities, they appear to be driven by different kinds of experiences when they endeavour to organize their classrooms. Originality/value - Never before has an active learning classroom been the site for a participatory furniture arrangement workshop that employs teachers and students.

Early Steps in Automated Behavior Mapping via Indoor Sensors
(MDPI, 2017) Arsan, Taner; Kepez, Orçun
Behavior mapping (BM) is a spatial data collection technique in which the locational and behavioral information of a user is noted on a plan layout of the studied environment. Among many indoor positioning technologies we chose Wi-Fi BLE beacon and ultra-wide band (UWB) sensor technologies for their popularity and investigated their applicability in BM. We tested three technologies for error ranges and found an average error of 1.39 m for Wi-Fi in a 36 m(2) test area (6m x 6 m) 0.86 m for the BLE beacon in a 37.44 m(2) test area (9.6 m x 3.9 m) and 0.24 m for ultra-wide band sensors in a 36 m(2) test area (6 m x 6 m). We simulated the applicability of these error ranges for real-time locations by using a behavioral dataset collected from an active learning classroom. We used two UWB tags simultaneously by incorporating a custom-designed ceiling system in a new 39.76 m(2) test area (7.35 m x 5.41 m). We considered 26 observation points and collected data for 180 s for each point (total 4680) with an average error of 0.2072 m for 23 points inside the test area. Finally we demonstrated the use of ultra-wide band sensor technology for BM.

Filling an Urban Void as a ‘public Interior’ in Balıkesir; Contemporary Intervention Into Historic Context Through Interior Space
(İstanbul Teknik Üniversitesi, 2017) Çetin, Murat
The paper argues the role of interior spaces in linking with the urban open space configuration. The interior space is discussed as extensions of urban spaces and urban spaces as extensions of interiors with specific reference to a case study selected in Balıkesir urban fabric. Under the light shed by these discussions, the paper questions the certainty of boundries between exterior and interior, thus between interior design and architecture. While the first axis of discussion focuses on the duality between interior and exterior, the second axis of discussion concentrates on the insertion of new and contemporary architectural and spatial features into an existing and historic context. The Museum and Library of Photography project in Balıkesir, which is selected as case study, is based on a VOID connecting what exists with what disappeared long ago in a totally new combination. Consequently, paper shows that architectural identity of the existing (and sometimes disappeared) heritage is reproduced via injection of this new hybrid (interior-exterior) into the very heart of the existing urban fabric. The hybrid design of the VOID intends to resolve the tensions between the contrasting features of restoration and intervention merely by understanding the conditions and fundementals of the process of historical layering in the town.
London 2012 Olympic and Paralympic Games-Acoustic Design Aspects of Temporary Venues
(European Acoustics Association EAA, 2014) Şaher, Konca; Cahill, Ben
This paper concentrates on the acoustic design aspects of the Temporary Venues at London 2012 Olympic and Paralympic Games. The project needed integration of individuals from various different client groups consultants and contractors into one team to work in a multi-disciplinary way. Atkins-Acoustics Noise and Vibration Consultancy worked with venue design team project managers sustainability consultants from London Organizing Committee of the Olympic and Paralympic Games (LOCOG) and architects. The keywords for Temporary Venues are absence of legacy and sustainability. There are over 120 of Temporary Venues spread throughout London and other parts of UK. The acoustic analysis strategy had two main components: Noise to the environment and noise to the venue. Noise to the environment included baseline noise survey of the site in comparison to the 3D modelling of the venue for construction games and demolition phases. Noise to the venue included setting acoustic criteria for each component sound insulation reverberation time calculations public address and voice evacuation design and mechanical plant noise control.
Mountain Bike Venue Test Event Noise Assessment London 2012 Olympic and Paralympic Games
(Studıo D-Akustika Sro, 2016) Şaher, Konca
This article reports the results of the noise monitoring during the London 2012 Mountain Biking Test Event which was held at Hadleigh Farm. The noise monitoring was held during the Mountain Bike Test Event for two purposes: Firstly as part of the requirements of Environmental Management Plan for the Test Event to ensure that no noise disturbance was being caused and the noise levels were below the agreed criterion of 65 dB(A) at the noise sensitive receptors during the Test Event and secondly to check whether any additional mitigation measures need to be adopted for the main Olympic Event. The noise monitoring results indicate that the L-Aeq noise levels at the selected two noise sensitive receptors were below the 65 dB(A) criterion. The results confirmed the predictions that the crowd noise was not a noise nuisance during the Test Event and the results further showed that no noise nuisance at the noise sensitive receptors was caused by public adress system. The public address system to be used during the main event was very similar to the Test Event therefore it was possible to conclude that the noise nuisance from the event (public address system and spectator noise) could be assessed as being moderate to low risk during the main Games.

Noise Annoyance During Covid-19 Lockdown: a Research of Public Opinion Before and During the Pandemic
(Acoustical Society of America, 2020) Şentop Dümen, Ayça; Şaher, Konca
Strict lockdown strategies to stop the spread of COVID-19 have caused a decrease in environmental noise levels and introduced new noise conditions in dwellings. The present study has investigated the impact of the forced lockdown in Turkey on noise annoyances due to traffic, neighbors, and personal dwellings, as well as the concern of being heard by neighbors, and overall dwelling satisfaction in an online questionnaire. The stress and anxiety levels of respondents were also investigated. The survey obtained 1053 respondents. Additionally, environmental noise levels were measured over 24-h at two locations and compared with results before the pandemic. The results clearly exhibit that environmental noise levels and annoyance due to the noise levels dropped significantly. The annoyance drop was larger in previously noisier environments than previously tranquil locations. Noise annoyance due to neighbor noise did not change significantly; however, noise annoyance due to one's own dwelling increased. The results also confirmed an overall increase in dwelling satisfactions indicating a correlation between dwelling satisfaction and lower environmental noise levels. Although the results confirmed that noise annoyance was positively correlated with stress and anxiety levels, the change of annoyance between before and during lockdown was shown to be independent from the stress and anxiety level

Room Acoustic Modelling of a Reverberation Chamber
(German Acoustical Society (DEGA), 2016) Şaher, Konca; Nas, Sezin; Karaböce, Baki; Kırbaş, Cafer; Bilgiç, Eyüp
This paper aims at comparing measured broadband reverberation time values in the reverberation chamber of Scientific and Technological Research Council of Turkey - National Metrology Institute (TUBITAK-UME) in Gebze Turkey with the simulated reverberation time values from the room acoustical modelling of the same reverberation chamber. The reverberation chamber in TUBITAK-UME has a volume of 263m3 total inner surface area of 262 m2 and 16 diffusers made of Plexiglas and hung randomly in the room. The majority of the diffusers have hyperbolic shapes. There are also six absorbers to adjust the reverberation time of the room. Indications of difficulties in the calibration of the acoustic model with reference to the measured values and different frequencies are given and the modelling and measurement uncertainties and limitations are discussed. © 2016 German Acoustical Society (DEGA).

(Ahmet Yesevi University, 2017) Keskin, Mustafa Çağhan
Born as the daughter of the serbian Knez Lazar taken into the Ottoman palace marrying Bayezid I (The Thunderbolt) who gave her father's execution order became the slave of Timur (Tamerlane) after the Battle of Ankara and when set free turning back to her country Olivera had a life full of trauma and tragedies resembling a romantic adventure According to the serbian she was a hero who sacrificed herself for her country according to the Ottomans she was a bad woman who adapted Bayezid to alcohol and entertainment according to European orientalist myths she was a princess who was despised by barbarians to whom was taken captive. This study aims to reveal the image of Olivera reflected in the works of contemporary Ottoman Byzantine Serbian Timurid and European sources narratives and arts with a focus on the life story of Olivera who although was essentially a member of the Ottoman dynasty did not have any monographs about her in Turkey.
