Online education became mandatory for many students during the Coronavirus disease 2019 (COVID-19) pandemic and blurred distinction between settings where processes of stress restoration used to take place. The lockdown also likely changed perceptions indoor acoustic environment (i.e., soundscape) raised its importance. In present study, we seek understand how soundscape related university students' self-rated health in Bulgaria around time that country was under a state emergency declaration caused by COVID-19 pandemic.Between 17 May 10 June 2020, conducted cross-sectional online survey among 323 (median age 21 years; 31% male) from two universities city Plovdiv, Bulgaria. Self-rated (SRH) measured with single-item. Participants were asked frequently they heard different types sounds while at home pleasant considered each those be. Restorative quality (the "being away" dimension Perceived Restorativeness Scale) A priori confounders effect modifiers included sociodemographics, house-related characteristics, general sensitivity environmental influences, mental health. Our analysis strategy involved sequential exploratory factor (EFA), multivariate linear ordinal regressions, modification tests, structural equation modeling (SEM).EFA supported grouping perceived into three distinct factors-mechanical, human, nature sounds. Regression analyses revealed greater exposure mechanical consistently associated worse SRH, whereas no significant associations found human SEM, lower restorative home, then poorer correlated higher quality, turn better SRH.These findings suggest role positive promoting times social distancing.

Abstract Comprehending the teacher’s message when other students are chatting is challenging. Even though sound environment same for a whole class, differences in individual performance can be observed, which might depend on variety of personal factors and their specific interaction with listening condition. This study was designed to explore role characteristics (reading comprehension, inhibitory control, noise sensitivity) primary school children perform comprehension task presence two-talker masker. The results indicated that this type impairs children’s accuracy, effort, motivation during task. Its impact depended level modulated by child’s characteristics. In particular, reading found support whereas control moderated effect condition two measures effort included (response time self-ratings), even different pattern association. A moderation sensitivity perceived also observed. Understanding relationship between classroom has practical implications acoustic design spaces promoting students’ well-being, supporting learning performance.

Despite being an overall objective of European policies, health equity and environmental justice have not yet been systematically implemented in policies. Taking control over one's environment as element equity, we consider intractable exposure to transportation noise a highly relevant policy field. The Environmental Noise Directive is designed sectoral dealing with one determinant (noise) drawing on the Global Burden Disease framework, whereas demands investigation manifold variations population by combining adverse salutogenetic (psycho-)social resources. Such resources or lack thereof referred 'non-acoustic factors' noise- soundscape-related research can presumably account for vulnerability caused social determinants. Thus, aim link current discourse driven need go beyond average exposure–response-relations. After summarising challenges noise-related impact assessment from perspective, focus residents' – both procedurally environmentally illustrate how determinants cause vulnerability.

Sounds (e.g., human activity, nature, building systems) are one of the indoor environmental stimuli that may have positive and/or negative effects on students’ well-being and performance in educational buildings. Students buildings individual acoustical preferences needs as portrayed by occupant-related indicators, for example perception. Acoustical guidelines generally focused terms dose-related sound pressure level) building-related indicators absorbing walls), while heart rate) rarely mentioned. In contrast, previous studies such soundscape studies, do take into consideration including physiological psychological. Therefore, this study aimed at summarizing these a comprehensive overview is essential investigating A literature review relevant domain acoustics was carried out. number key (occupant-related, dose-related, building-related) methods fundamental to be considered were identified. Only few investigated considering (both psychological). addition, other quality (IEQ) factors taken account studies.
