“…Methods such as "grounded theory" coupled with interviews have been specifically investigated in the field of indoor soundscapes, to systematically extract information on subjective perception from qualitative data gathered during questionnaires or interviews [60][61][62]. Several studies have addressed the perception of acoustic environments in specific building types, such as: residential buildings [51,57,63], offices [60,64], libraries [53,65], care facilities [66][67][68], study spaces [69], historical buildings [61,62], restaurants [70], shopping malls [71,72], and public transport spaces [73]. Table 1 provides insight into these selected studies.…”

Acoustic Design Criteria in Naturally Ventilated Residential Buildings: New Research Perspectives by Applying the Indoor Soundscape Approach

et al. 2019

The indoor-outdoor connection provided by ventilation openings has been so far a limiting factor in the use of natural ventilation (NV), due to the apparent conflict between ventilation needs and the intrusion of external noise. This limiting factor impedes naturally ventilated buildings meeting the acoustic criteria set by standards and rating protocols, which are reviewed in this paper for residential buildings. The criteria reflect a general effort to minimize noise annoyance by reducing indoor sound levels, typically without a distinction based on a ventilation strategy. Research has developed a number of solutions, discussed here, that try to guarantee ventilation without compromising façade noise insulation, but, currently, none have been adopted on a large scale. This concept paper highlights the main limits of the current approach. First, a fragmented view towards indoor environmental quality has not included consideration of the following acoustic criteria: (i) how buildings are designed and operated to meet multiple needs other than acoustical ones (e.g., ventilation, visual, and cooling needs) and (ii) how people respond to multiple simultaneous environmental factors. Secondly, the lack of a perceptual perspective has led acoustic criteria to neglect the multiple cognitive and behavioral factors impinging on comfort in naturally ventilated houses. Indeed, factors such as the connection with the outside and the sense of control over one’s environment may induce “adaptive acoustic comfort” opportunities that are worth investigating. The mere use of different sound level limits would not be enough to define criteria tailored to the complex user–building interaction that occurs under NV conditions. More holistic and human-centered approaches are required to guarantee not only neutrally but even positively perceived indoor acoustic environments. For this reason, this paper considers this apparent conflict from a soundscape viewpoint, in order to expose still unexplored lines of research. By underpinning a perceptual perspective and by contextualizing it, the indoor soundscape approach provides a framework capable of overcoming the limits of the traditional noise control approach. This could provide the opportunity to foster a wider adoption of NV as a passive design strategy that enhances user health and well-being, while enabling low-cost, and low-energy cooling and ventilation, thereby contributing to current climate change challenges.

“…Previous studies on the categorization and quantification of soundscapes mostly rely on assessments of participant perceptions. In these studies (Acun and Yilmazer, 2018;Bruce and Davies, 2014;Mackrill et al, 2013;Maristany et al, 2016), participants are usually guided to participate in questionnaires about soundscapes. For example, based on investigations, Yilmazer and Acun (2018) explore the relationship among the sound factors, spatial functions, and properties of soundscapes.…”

Soundscape studies typically attempt to capture the perception and understanding of sonic environments by surveying users. However, for long-term monitoring or assessing interventions, sound-signal-based approaches are required. To this end, most previous research focused on psycho-acoustic quantities or automatic sound recognition. Few attempts were made to include appraisal (e.g., in circumplex frameworks). This paper proposes an artificial intelligence (AI)-based dual-branch convolutional neural network with cross-attention-based fusion (DCNN-CaF) to analyze automatic soundscape characterization, including sound recognition and appraisal. Using the DeLTA dataset containing human-annotated sound source labels and perceived annoyance, the DCNN-CaF is proposed to perform sound source classification (SSC) and human-perceived annoyance rating prediction (ARP). Experimental findings indicate that (1) the proposed DCNN-CaF using loudness and Mel features outperforms the DCNN-CaF using only one of them. (2) The proposed DCNN-CaF with cross-attention fusion outperforms other typical AI-based models and soundscape-related traditional machine learning methods on the SSC and ARP tasks. (3) Correlation analysis reveals that the relationship between sound sources and annoyance is similar for humans and the proposed AI-based DCNN-CaF model. (4) Generalization tests show that the proposed model's ARP in the presence of model-unknown sound sources is consistent with expert expectations and can explain previous findings from the literature on soundscape augmentation.

“…According to this, there are eight soundscape descriptors: noise annoyance, pleasantness, quietness or tranquillity, music-likeness, perceived affective quality, restrictiveness, soundscape quality, and appropriateness. Data regarding this descriptors can be collected with various tools: questionnaires [8,9], semantic scales [10][11][12], interviews protocols [8,[13][14][15][16][17], binaural recordings and/or psychoacoustic measurements [18].…”

“…While the urban soundscapes have been investigated over the decades, the indoor soundscape studies begun more recently. So far, indoor soundscape research covered a variety of different indoor soundscapes [19], such as hospitals [8], open-offices [16], education facilities [10,20], care facilities [21], libraries [22][23][24], worship places [15], transportation hubs [25]. One of the first examples of indoor soundscape research has been conducted by Mackrill et al, when they used qualitative methods to capture the subjective soundscape perception of a hospital ward.…”

“…Another GT research conducted by Yilmazer and Acun investigated the soundscape of the historic Hacı Bayram Mosque of Ankara, which showed the associations between the soundscape elements, spatial function and place identity [15]. Another indoor soundscape research is carried out in the study areas of a university to investigate the sound sources, users' reactions, coping methods as well as the perceptual dimensions of the indoor soundscape [10]. Yilmazer and Bora gathered new research results dealing with the indoor soundscape in the metro station including urban soundscape and showed how a built environment affects the pedestrians/passengers and how they perceived their auditory environment.…”
