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.Article Assessment of speech intelligibility during different teaching activities in classrooms with and without acoustic treatment(Elsevier Sci Ltd, 2023) Şaher, Konca; Bulunuz, Mizrap; Kelmendi, Jonida; Nas, SezinThere is limited data for assessing speech intelligibility in real classrooms with realistic occupied noise levels and teacher's and students' speech levels for different teaching activities in Turkish secondary school classrooms. This study investigates the effect of reverberation time (RT), occupied noise levels and signal-to-noise ratio (SNR) on speech transmission index (STI) in real classrooms for instruction and group work. Noise levels were measured and STI values were calculated in two secondary school classrooms with RT of 0.88 s and 2.73 s. During instruction situation, calculated mean STI values were 0.63 (classroom with acoustic treatment) and 0.29 (classroom without acoustic treatment) for normal voice effort and 0.65 (classroom with acoustic treatment) and 0.39 (classroom without acoustic treatment) for raised voice effort. During group work, STI values ranged from 0.50 to 0.74 in classroom with acoustic treatment and from 0.01 to 0.34 in classroom without any acoustic treatment. SNR of 15 dBA is only approached in classroom with acoustic treatment during instruction situation. The effect of increasing SNR on STI is prominent in the classroom without acoustic treatment which already has low SNR values. The present results show that the classroom with acoustic treatment will have good speech intelligibility for instruction with normal vocal effort and for group work with raised vocal effort at 3 m distance. However, the classroom with no acoustic treatment will have STI values in the range of bad and poor intelligibility. The present results confirm the impact of SNR and RT on speech intelligibility and shows that RT value of minimum 0.8 s is optimal to have good speech intelligibility in a secondary school classroom of approximately 250 m3 with a capacity of 18 students.(c) 2023 Elsevier Ltd.

However, these unprecedented times and activities around the world, which explored the interaction between sound, technology and the society, presented sound experiences for humanity and the ecosystem that they have never had the opportunity to experience before. This study reports on the activities of Turkish Acoustical Society during these times and aims to draw attention to the benefits, challenges, and opportunities of the instruments for widening participation and spreading knowledge relating to sound. The main activities were public opinion survey on noise annoyance in dwellings before and during the pandemic, Turkish Glossary of Acoustic Terms, IYS Drawing and Composition Competition in Turkish schools and various seminars, interviews, podcast on social media channels. Our experience and findings suggest that designing and implementing activities that actively includes researchers, teachers, students and ordinary people may help increase public engagement behaviorally, emotionally, and cognitively, there by positively affecting awareness in sound related subjects. © 2023 First author et al.

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.Conference Object Towards New Acoustic Policies in the 'new Normal' of the Covid-19 Pandemic(International Commission for Acoustics (ICA), 2022) Şentop Dümen, A.; Şaher, Konca; Şaher, K.; Kurra, S.In 2020, Turkish Acoustical Society conducted a survey to measure the pandemic's impact on acoustic evaluation of residential buildings. 1053 people participated in this survey and answered to the questions on their noise annoyances before and during the Covid-19. Results indicated an increased acoustical comfort during the lock-downs due to the decreased environmental noise, but also highlighted the importance of interior noises (from neighbouring dwellings and from one's own dwelling). Other studies from all over the world reported similar results for the first wave of the pandemics. After two years of experience, the question of how user behaviour, acoustical perception and expectance have changed is yet to be answered in order to develop correct strategies and strengthen the acoustical policies for accomplishing sustainable cities. This paper introduces the results of the 2020 study and gives an analysis of the current literature on (1) acoustic perception during the pandemics, (2) working from home and its persistency, and (3) changed user habits in dwellings and in cities. The acoustical requirements in the era of 'new normal' and policy implications are discussed. © ICA 2022.All rights reservedConference Object Blending Science and Art: an Educational Perspective(Iated-Int Assoc Technology Education & Development, 2019) Balkır Kuru, Nur; Şaher, Konca; Şaher, Konca; Balkır, Nur; Mıhçı, Gürkanrt and design education enable students to find creative and logical solutions to various design problems. The use of materials, constructive analysis, craftmanship, and originality are some key criteria in the process. Size and dimensionality, the proportion analysis, expression integrity, substantiality, and presentability can vary depending on the project and the context. As one of the methods used to provide targeted experience and learning in art and design education, interdisciplinary work presents a right ground for complex design issues. The workshop we carried out together with the Tubitak National Metrology Institution (UME) named "Art's Metrology, Metrology's Art" aimed to transform art, design, and science together into a product. As rational, natural, and appropriate connections can be established between art and science, students were asked to develop a method to meet the objectives and criteria of both around a certain conceptual focus. An important inclusive of the workshop was to have students observe, get informed, and engage in dialogue and ultimately increase their curiosity about a certain mechanism outside of their studies. The group dynamic in the process of creating three-dimensional and displayable works within a scheduled time was supported by a scientist from the metrology department, three art and design instructors, Konca Saher, Nur Balkir, and Gurkan Mihci from Kadir Has University. The finished works were then exhibited in the Tubitak-UME in Gebze compound. This study, which blends science and art, provided students with the opportunity to experiment with a science field, and to develop their predictions about their own disciplines. The paper will present the development and the outcome of the workshop.Conference Object EXPLORING THE ACOUSTIC IDENTITY OF DERINKUYU UNDERGROUND CITY(Society of Acoustics, 2024) Nas,S.; Şaher, Konca; Şaher,K.; Mıhçı,G.; Aytıs,S.Sounds play a significant role in shaping the identity of spaces and places, yet the acoustic environment of underground cities remains relatively unexplored in the existing literature. Derinkuyu Underground City stands as a prominent cultural heritage site, boasting a capacity of 20,000 people and serving as one of the largest underground cities globally. While geological and structural studies have been conducted on such sites, investigations into indoor acoustics, a crucial aspect of the physical environment, are notably lacking. This study initiates an initial examination of the sound environment within Derinkuyu Underground City, aiming to analyse its features acoustically. Undertaking a PhD study, our research endeavours to gather essential data essential for the preservation of the site's current acoustic environment as a cultural heritage site while also generating valuable insights for the design and construction of future underground cities. In this paper, we present a preliminary assessment of the typologies of various spaces within Derinkuyu Underground City, exploring their unique acoustic features. By characterizing and understanding the acoustic properties of diverse spaces within the underground city, we seek to understand how acoustic might contribute to the identity of these spaces and provide foundational knowledge for both preservation efforts and future underground urban design initiatives. © 2024 Proceedings of the International Congress on Sound and Vibration.

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).
