    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.

    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.
