Book Part Indoor Soundscapes of the Future: Listening To Smart Houses(wiley, 2023) Alkan, A.L.; Yörükoğlu, P.N.D.; Kitapci, K.The acoustic environment of smart houses impacts the overall quality of life and wellbeing of occupants. A well-designed acoustic environment can promote relaxation, while excessive noise or distractions can negatively impact wellbeing. It is crucial to consider sound’s role in smart house design. Smart houses have built-in virtual assistants that respond to voice commands, perform various tasks, and verbally respond to such commands. This machine-to-human-to-machine verbal interaction requires high speech intelligibility (i.e., low reverberation time and high signal-to-noise ratio) in smart houses, which is not required for traditional homes. The open floor plan and multi-purpose rooms in smart houses can create challenges for sound management. This can be addressed by creating separate zones for different activities or using room dividers that help to direct and absorb sound. The design of smart houses includes the placement of speakers and other audio devices to optimize sound quality and distribution. Speakers are installed in the ceiling or walls to create a more immersive and balanced listening experience. The placement of microphones and other sensors should also be optimized for smart houses. Microphones should be placed where sound is most likely heard or where it best captures voice commands. Integrating multiple audio sources and devices creates challenges in managing and organizing sound in a smart house. Designers should consider configuring smart devices and ensuring that different devices are compatible and functioning properly. © 2024 by John Wiley & Sons, Inc.

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.

The research was conducted in a real open-plan office environment to include the open-office experience of subjects to the analysis. STM Bilkent Office was selected as the case, and 40 available open-office occupants were participated to the study. The experiment consists of two main phases. In the first phase, acoustical simulation of the site was done, to derive distribution graphs for speech related room acoustics parameters. In the second phase, occupants’ computer-based task performances were tested under three different sound environments, which are continuous noise, speech and masked speech. According to statistical analysis of the performance test, and the acoustical properties of the case STM, suggestions for renovation were discussed. It was found that effects of intelligible speech on occupants’ task performance are only psychological, because it is significant that there is no difference between results of performance test. However, all of the occupants respond to the questionnaires that speech sound environment was the most distracting one. Proposal for renovation was given to minimize the effects of intelligible speech on occupants for preventing the long-term effects on occupants’ health.Conference Object Categorization of urban sound sources: A taxonomical framework based on diegesis and intention(2021) Kitapçı, Kıvanç; Özdemir, DoğukanThe sound source composition of the urban sound environment varies depending on the geography and socio-cultural context. Current sound taxonomies in the literature categorize urban sound sources by their source types (e.g., human-made, natural, electromechanical) and respective semantic attributes. This study aims to add another taxonomical layer to the existing urban sound source categorization methods. The additional layer is a recently proposed sound source classification framework (CLIC). The CLIC framework identifies sound sources based on their Diegesis and Intention parametric attributes. The former parametric attribute, diegesis, was derived from film sound design. The geographical and socio-cultural context of the built environment can be considered as its narrative; hence, every event that happens within the functional context can be called diegetic, while the events that do not belong to that specific place can be called nondiegetic. The latter parametric attribute, intention, was derived from product design. One of the prominent sound source categorization methods in product sound design is to group the product emitted sounds as consequential and intentional. Combining these two parametric attributes with the existing taxonomies, the CLIC framework outputs a place-specific design guideline, clearly dictating the actions a sound designer should take. The two parametric attributes group the sound sources under four distinct areas, which dictates the degree of influence of designers on the specific sound source. The four zones are defined as the creation zone, limitation zone, isolation zone, and control zone. Each zone dictates step-by-step sound design instructions for the sound designer. This study consists of two main phases: field recordings and web-based listening tests. The sound sources present in the urban sound environment were identified in the field recordings phase. Later, in the web-based listening tests phase, the identified sound sources were evaluated based on the CLIC framework, and hence, their respective zones on the model were identified. The outcomes of the study propose clear step-by-step design guidelines and present action suggestions for environmental sound designers.Article Citation - WoS: 1Citation - Scopus: 2Impact of Indoor Soundscape Workshop on Sound Awareness of Interior Architecture Studentsa)(Acoustical Soc Amer Amer inst Physics, 2025) Al-Bayyar, Zinah; Yorukoglu, Papatya Nur Dokmeci; Kitapci, Kivanc; Bayrak, Ozlem TurkerThis study aims to investigate the effects of attending a soundscape workshop on the awareness of sound as a design element for interior architects. The workshop is structured in three phases: theoretical lectures, practical applications, and discussions. In the first phase, fundamentals of architectural acoustics, the sense of place, and soundscape theory were delivered through theoretical lectures. In the second phase, participants were asked to design a sound environment for a restaurant and an office. In the third and final phase, participants discussed their sound designs from the perspectives of the lectures and sound-related topics. Additionally, participants completed an open-ended questionnaire to evaluate their workshop experience and provided suggestions for improvement. The effectiveness of the workshop in raising awareness was tested using a pre-test/post-test analysis method, with data collected through structured questionnaires completed by participants before and after the workshop. The results of the statistical analysis show that attending the workshop changed participants' evaluations of sound expectations and preferences, as well as their sensitivity to sound. The findings indicate that participating in an indoor soundscape workshop can positively influence interior architects' understanding of sound as a design element to be considered in their future work. (C) 2025 Acoustical Society of America.Conference Object Citation - Scopus: 1An Interdisciplinary Sound Source Categorization Framework for Environmental Sound Design(The Institute of Noise Control Engineering of the USA, Inc., 2021) Kitapci, K.; Ozdemir, D.One of the objectives of architectural design is to create multisensory environments. The users are under the influence of a wide variety and intense perceptual data flow when users experience a designed space. Architects and environmental designers should not ignore the sense of hearing, one of the most important of the five primitive senses that allow us to experience the physical environment within the framework of creative thinking from the first stage of the design process. Today, auditory analysis of spaces has been studied under architectural acoustics, soundscapes, multisensory interactions, and sense of place. However, the current sound design methods implemented in the film and video game industries and industrial design have not been used in architectural design practices. Sound design is the art and application of making soundtracks in various disciplines, and it involves recognizing, acquiring, or developing auditory components. This research aims to establish a holistic architectural sound design framework based on the previous sound classification and taxonomic models found in the literature. The proposed sound design framework will help the architects and environmental designers classify the sound elements in the built environment and provide holistic environmental sound design guidelines depending on the spaces' functions and context. © INTER-NOISE 2021 .All right reserved.Conference Object Reconstructing the Soundscape of the Ancient Hippodrome of Olympia for an Immersive Sonic Experience of the Site Based on Sound Sources Description in Texts(Société Française d’Acoustique, 2024) Al-Bayyar, Zinah; Dokmeci Yorukoglu, Papatya Nur; Kitapci, Kivanc; Çelebi, GülserThis study attempts to reconstruct and auralize the soundscape of the Hippodrome of Olympia in Greece. This UNESCO world-heritage-listed-site is considered the evidence of the Greek hippodromes. Hippodromes used to have several activities from which different combinations of sound sources created the soundscape. To collect sound sources, description in texts of site is sought by implementing methods of the archaeology of soundscape and the suggested criteria of contextual, internal, and comparative certainty for archaeoacoustics studies. The description of these activities facilitates reconstructing and auralizing the soundscape during different phases of events in the hippodrome. The results of the study showed that the information about the activities on the hippodrome, on similar hippodromes of different civilizations, and on similar hippodromes of later eras are rather sufficient to create a comprehensive soundscape of the site. Auralizing the reconstructed soundscape by using current auralization software and techniques promises of immersive experience of ancient sites that enhances understanding the sonic intangible cultural heritage element and the experience of the ancient soundscape. Furthermore, ancient users’ perception of the soundscape can be approached by localizing the sound sources on the site and obtaining the corresponding acoustical properties, providing information of users’ response to the sonic. © 2025 Elsevier B.V., All rights reserved.Conference Object Citation - Scopus: 7Room Acoustics Education in Interior Architecture Programs: a Course Structure Proposal(SOCIEDAD ESPANOLA DE ACUSTICA - Spanish Acoustical Society, SEA, 2019) Kitapcı, Kıvanç; Kitapci, K.; İç MimarlıkSoundscape 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.

Listening tests were used to evaluate three acoustic environments (an airport, a hospital, and a caf) under three room acoustic conditions defined by a different speech transmission index (STI) (STI = 0.4, 0.5 and 0.6). In the tests, participants rated eleven semantic attributes representative of speech perception and the overall soundscape (speech intelligibility, speech level, speech pleasantness, noisiness, annoyance, relaxation, comfort, environment pleasantness, eventfulness, excitement, and familiarity). Results obtained indicate that inter-language comparisons based on perceived speech intelligibility are different from those obtained from objective speech intelligibility tests. Noticeably, English participants were found to be most sensitive to changes in room acoustic conditions and to meaningful and distractive noise sources, whilst Arab participants were least sensitive to changes in room acoustic conditions and more tolerant to noise. Perceived speech intelligibility correlated significantly with non-acoustical factors (speech pleasantness, comfort and environment pleasantness), and 'emotional factors' (annoyance, relaxation, comfort and environment pleasantness) explained a large portion of the variance in soundscape assessment. Results also showed that language affected the perceived speech intelligibility marginally (p = 0.051) and noisiness significantly (p = 0.047), the latter being the best indicator of cultural variations amongst the attributes tested. Overall, the study shows that designing for speech intelligibility cannot be solely based on room acoustic parameters, especially in the case of multi-lingual environments. (C) 2019 Elsevier Ltd.

The experiments were conducted in the private lecturer offices located in the Faculty of Architecture, cankaya University. The sense of place of 15 participants was tested in the original offices of each participant and eight additional acoustic auralisations, in which reverberation times and sound source compositions were modified. The analysis of the results revealed that there is a direct influence of reverberation time and sound source composition on the sense of place. It was observed that longer reverberation times partially enhanced the sense of place. Additionally, the sound source composition influenced the relation towards the place, and certain sound signals diminished the sense of place in the private offices. Furthermore, this study used a psychophysical scaling method (Absolute Magnitude Estimation scale [AME]) which indicated its validity and importance in investigating the effect of physical stimuli on the sense of place. The AME revealed the sense of place by directing the influence towards the place construct indicators rather than investigating the general relation towards the place. It was concluded that reverberation time and sound source compositions could enhance and/or diminish sense of place; hence, RT and sound source compositions can affect interpretation of and behavior towards a given place.
