    Soundscape Assessment: Towards a Validated Translation of Perceptual Attributes in Different Languages
    (Korean Society of Noise and Vibration Engineering, 2020) Aletta, F.; Oberman, T.; Axelsson, Ö.; Xie, H.; Zhang, Y.; Lau, S.-K.; Kang, J.
    The recently published ISO/TS 12913-2:2018 standard aims to provide researchers and practitioners around the world with a reliable questionnaire for soundscape characterization. The ISO Technical Specifications report protocols and attributes grounded in the soundscape literature, but only includes an English version. The applicability and reliability of these attributes in non-English speaking regions remains an open question, as research investigating translations of soundscape attributes is limited. To address this gap, an international collaboration was initiated with soundscape researchers from all over the world. Translation into 15 different languages, obtained through focus groups and panels of experts in soundscape studies, are proposed. The main challenges and outcomes of this preliminary exercise are discussed. The long-term objective is to validate the proposed translations using standardized listening experiments in different languages and geographical regions as a way to promote a widespread use of the soundscape attributes, both in academia and practice, across locations, populations and languages. © Proceedings of 2020 International Congress on Noise Control Engineering, INTER-NOISE 2020.

    Room Acoustics Education in Interior Architecture Programs: a Course Structure Proposal
    (SOCIEDAD ESPANOLA DE ACUSTICA - Spanish Acoustical Society, SEA, 2019) Kitapcı, Kıvanç; Kitapci, K.; İç Mimarlık
    Soundscape research alters the notion of room acoustics from a physical phenomenon to a new multidisciplinary approach that concerns human perception of the acoustic environment, in addition to the physical calculations and measurements. Many interior architecture programs include courses that specifically focus on room acoustics. Although a brief introduction to the technical aspects of room acoustics is considered mandatory, the current course structure does not deliver sufficient information on the human perception of the acoustic environment. Therefore, the aim of the study is to reconsider the structure of room acoustic courses and present a brand-new room acoustics course structure proposal for the interior architecture programs. The study consists of two main phases. In the first phase, a database of all courses that include various topics on room acoustics is prepared through examination of the course descriptions of all undergraduate and graduate interior architecture programs in Turkey. In the second phase, the revisions to the current state of the room acoustics course structures are advised through an in-depth systematic literature review on the research area of soundscapes. Preliminary results and the initial course structure model will be presented at the conference. © INTER-NOISE 2019 MADRID - 48th International Congress and Exhibition on Noise Control Engineering.

    An Investigation of Sound Sources in Smart Houses for Improved Machine-To Communication
    (European Acoustics Association, EAA, 2023) Kitapcı, Kıvanç; Alkan, A.; Yorukoglu, P.N.D.; Kitapci, K.; İç Mimarlık
    This study aims to investigate the ever-evolving indoor soundscapes of smart houses by classification of the sounds emitted from smart devices. Nowadays, communication is no longer limited to person-to-person. Smart devices frequently communicate with users by verbal or tonal notifications. Therefore, acoustic characteristics of smart houses, especially reverberation time and background noise levels, have increased importance in achieving improved and lossless signal transfer and speech intelligibility. It is hypothesized that most houses are unsuitable for effective tonal and verbal communication with smart devices regarding acoustical conditions. Within the scope of the study, the devices found in the smart technology market were investigated. The sounds emitted from the identified devices were then classified according to their communicative nature (verbal/tonal), designability, customizability, and cause (i.e., intentional or consequential). The acoustic requirements for effective communication with the individual smart devices were analyzed in addition to the resulting holistic indoor soundscape of the smart houses The results of the study will help architects, interior architects, and other environmental designers to improve the quality of communication while guiding future research to understand indoor soundscapes of smart houses. © 2023 First author et al.

    A Taxonomy of Indoor Acoustic Environments and Sound Source Preference in Shopping Centres
    (Korean Society of Noise and Vibration Engineering, 2020) Yörükoğlu, Papatya Nur; Erçakmak, U.B.; Dökmeci Yörükoglu, P.N.; İç Mimarlık
    As part of soundscape research, sound source classification and taxonomy studies play an important role in relation with contextual experience and user perception. Although, outdoor acoustic environments have been studied in detail, published and standardized in the literature, taxonomy studies on indoor acoustic environments are still at its preliminary phase and should be progressed. This study concentrates on shopping centre indoor acoustic environments and presents a preliminary proposal on the indoor sound source taxonomy of such indoor public spaces. The presented taxonomy and the structured classification of the sound sources lead to the preparation of a structured surveying protocol. Thereby, the sound source preference in the case shopping centre has been studied through this structured indoor soundscape preference assessment questionnaire, which is applied to 19 participants. The indoor sound source taxonomy lead to the identification of the sound sources to be included in the structured preference assessment questionnaire. 23 sound sources and the overall sound environment have been assessed through a bi-polar 6-point forced-choice rating scale. The results of the questionnaire have led to the identification of the most and least preferred sound sources in shopping centres, which can act as key elements in the design phase of such public enclosed environments. © Proceedings of 2020 International Congress on Noise Control Engineering, INTER-NOISE 2020.

    Spatial Design Outcomes of Indoor Soundscaping Course as Part of Interior Architecture Education
    (The Institute of Noise Control Engineering of the USA, Inc., 2022) Yörükoğlu, Papatya Nur; Yörükoğlu, P.N.D.; İç Mimarlık
    Indoor soundscaping is a multi-disciplinary field that integrates, sound, user experience, and architecture. At its core, it has the potential to redefine any enclosed acoustic environment. Listening to spaces should be an active act of an interior architect; an awareness that should be gained during the early years of interior architecture undergraduate education. The elective course with the same name, 'Listening to Spaces' has been offered to interior architecture students since 2015 at Çankaya University, Ankara, Turkey under the Department of Interior Architecture, with the aim of implementing an important additional topic specific course to the present education curriculum of the Department as the course combines architectural, spatial and functional analysis methods from an acoustical perspective, in order to raise awareness on conscious listening of spaces with different functions. The course is conducted through interactive learning bases and the orientation is more research-based than teaching-based, although basic acoustical and soundscape theoretical knowledge is given. Students are expected to accomplish 6 tasks progressively following the cognitive process dimensions parallel to Bloom's taxonomy. The outcomes of the tasks and the final spatial design proposals has been evaluated and discussed as part of this study to highlight the importance of topic specific course integration to architectural design education. © 2022 Internoise 2022 - 51st International Congress and Exposition on Noise Control Engineering.

    Conceptual Framework for a Decision-Making Model Based on the Analytic Hierarchy Process (Ahp) To Select the Best Public Private Partnership (Ppp) Model for Airports
    (New Zealand Acad Applied Research Ltd, 2017) Mohammed, Ali Omar; Harputlugil, Timuçin; Harputlugil, Timucin; Mimarlık
    The adoption of public-private partnerships (PPPs) as a strategy for infrastructure projects, such as airports, highways, bridges, water supplies, and telecommunication, has been implemented in developed and developing countries with a number of obstacles. Based on this stance, critical success factors (CSFs) of public-private partnership projects and the selection of appropriate PPP models are critical issues that need to be analyzed. A multidisciplinary review of the literature on the critical success factors of public-private partnerships projects reveals the lack of a comprehensive decision-making model for selecting an appropriate PPP model. This paper presents a conceptual framework for a decision-making model to select the best PPP model considering CSFs for developing countries. The model is expected to be used for infrastructure projects, mostly for airports. The decision-making model is structured on the Analytic Hierarchy Process and sensitivity analysis. The decisionmaking model is expected to be adopted as a tool and contribute to decision makers for selecting the best fit PPP model for airports in order to enhance projects successfully.

    Impact of Complexity on Perceived Affective Quality and Perceived Restorativeness in Indoor Soundscapes
    (European Acoustics Association, EAA, 2023) Acun, V.; Aksel, Elif; Aksel, E.; İç Mimarlık
    Eventfulness and pleasantness are two prominent components of soundscape perception, and their interplay creates attributes that are used to measure the perceived affective quality of soundscapes. Even though restorativeness is not among the principal components of soundscape perception, it is involved with soundscapes' perceived affective quality attributes. While the contribution of these attributes is well established, there is still a lack of understanding regarding how soundscape complexity impacts perceived restorativeness and perceived affective quality. There are tools, such as the Acoustic Complexity Index, to measure the complexity of natural soundscapes but soundscapes of the built environment lack such an index. This study aims (1) to understand the relationship between complexity, perceived affective quality and perceived restorativeness and (2) to explore and compare the effectiveness of different means of measuring acoustical complexity. With this regard, we conducted an online questionnaire survey which consisted of twenty soundscape recordings. We asked the participants to evaluate the perceived affective quality and perceived restorativeness of each recording. We then calculated the acoustic complexity indices, Acoustic complexity, Acoustic Diversity, Acoustic Evenness, and Normalized Differences Soundscape Index. Finally, we conducted a series of statistical analyses to explore the relationships between each variable. © 2023 Acun et al.
