The human-nature connection should be a key component in the design of supportive and comfortable indoor environments. An interest introducing Nature Based Solutions via Biophilic Design (BD) intervention recently emerged. Related benefits for work efficiency have been identified lab-studies without possibility to perform preliminary assessments. Recently, VR has adopted thanks its advantages data collection highly realistic To date, most research on BD focused visual with nature even if people experience multiple senses simultaneously. In this paper, new approach assessment is presented. A 3x3 between-subjects study presented, comparing three office layouts (Indoor Green, Outdoor Green Non-Biophilic) acoustic scenarios (Office, Office + Traffic Nature). 198 participants performed one test session completing cognitive tasks each condition, survey. results sense presence immersivity (visual), sensory congruency (acoustic) cybersickness disorders suggested that an effective tool evaluate potential interventions (ecological validity). findings tests revealed audio-visual can positively influence working memory, inhibition task-switching performance. factor exhibited higher improvement effect compared factor, between 23 % 71 against 12 %–39 %. Moreover, Natural sound Indoor condition was visual*acoustic while Non-Biophilic environment disruptive one.

Soundscape research on indoor environments is emerging as a topic to be addressed for the design of supportive, healthier, and more comfortable spaces. Only few studies so far context educational buildings, mainly focusing high schools universities. This pilot study uses questionnaires based pictorial scales investigate soundscape classrooms primary school children (n = 130; 8-10 years old). Perceived loudness affective dimensions pleasantness arousal were explored. Besides actual soundscape, children's ideal was investigated well. The results indicate that most frequent sounds in are generated by students themselves (voices, movements) followed traffic. urban modulates perception when windows open ensure natural ventilation. Pleasantness associated with students' age, perceived loudness, frequency voices nearby classrooms. hearing (children's voices) sirens affects arousal. Our at mostly exposed unpleasant sounds, whereas their preferred ones music nature-related ones. findings have implications positive inclusive learning environments.

Neighbour noise affects health, emotions, behaviours, privacy and social relations. This paper aims to present residents’ perspective on neighbour initiate a discussion consumer rights protection based the results of media analysis. In 2021, two newspaper articles about acoustic labelling were published, receiving over 700 comments in media. A thematic analysis revealed experiences multi-storey housing, attitudes toward sources, responsibilities solutions. Considering heterogeneity apartment users needs, economic burden real estate transactions, difficulty redressing issues, we argue that performance disclosure, for example, through labelling, is an urgent necessity providing informed choices house-buyers tenants. The further indicate need address vulnerabilities certain groups, not only from exposure but also being overheard.
