“…Noise, which includes sound produced by human activities, has been intensively studied for its detrimental effects on human comfort, health, and productivity. 31 Physical workload combined with noise intensity that exceeds 85 dB(A) for 8 hours of work could lead to fatigue symptomps such reduced concentration, physical exhaustion, dizziness and others. 32,33 Yovi et al 27 stated that noisy environmental conditions can cause the operator to feel tired and lose their concentration easily.…”

Background: Noise has the potential to affect the comfort and health of workers. The objective of this research was to find out the effect of noise caused by the timber harvesting process using chainsaws on the concentration of workers in an industrial forest plantation. Methods: This experimental study included 20 respondents which consisted of 10 chainsaw operators/helpers and 10 non-chainsaw operators. All respondents were exposed to the sound of a chainsaw in three different conditions (idle, half gas and racing conditions) with and without personal protective equipment (PPE). The sound intensity produced by the chainsaw and the noise received by the respondents were measured using a sound level meter. Respondents’ perception toward noise was recorded using a Likert scale. Respondents’ concentration level was assessed by giving 25 math-questions to be answered within 10 minutes. Wilcoxon sign rank test was used to analysed paired data. Results: The average sound intensity received by respondents’ left and right ears were lower than the average sound intensity produced by the chainsaw. The use of earmuffs leads to better perception towards noise when compared with the use of earplugs and the absence of any PPE. The Wilcoxon test result showed that noise did not have significant impact on the concentration level of chainsaw operators, whilst the contrary result is true for non-chainsaw operators. Conclusions: The research indicated that although the noise produced by the chainsaw machine was considered noisy for both chainsaw operators and non-chainsaw operator, it did not have a significant effect on the concentration level of chainsaw operators and only affected the non-chainsaw operators. Therefore, given that the non-chainsaw operators were still affected by the noise, noise control measures are still needed to ensure occupational safety and health for the workers.

“…Environmental noise is a form of pollution that can have serious health consequences for populations repeatedly subjected to this exposure [4][5][6][7][8]. For example, in addition to causing hearing loss over time, it can also provoke high blood pressure and stress, which affects well-being and productivity [9,10].…”

This paper aims to present an interdisciplinary approach intended to raise awareness for Sustainable Development Goals in the context of STEM (Science, Technology, Engineering, and Mathematics) hands-on activities targeted to elementary and secondary school. In particular, contents related to the physics of sound are used to warn about the dangers of noise pollution and its consequences for health, well-being, and productivity. Therefore, it is crucial to inform and raise community awareness on this issue, as well as on the measures needed to prevent its consequences. This research is inserted in a broader pedagogical project that includes primary school and secondary school teachers’ professional development and visits to schools to perform several hands-on activities in class aiming to provide students with 21st-century skills related to STEM education. Based on the literature, questionnaires, and participant observation, an empirical study was conducted with teachers who participated in a professional development programme. It is concluded that teachers and students understood the dangers of noise pollution and the measures to be taken to prevent them. Therefore, higher education institutions have a crucial role in the community, namely, through partnerships with schools and teachers’ training centres to raise awareness and disseminate and increase Sustainable Development practices in the community.

“…In the specific case of office workers, previous research has highlighted several risks associated with the working behavior and environmental conditions for facility management that can affect the employees' mental health. While employees spend 90% of their time indoors, the environmental conditions in the workplace critically affect the employees' wellbeing and productivity [5]. Sun et al [6] explain that indoor air quality has a significant impact on the person's health, comfort, and performance.…”

The fast-paced business environment and new work arrangements have elevated mental health risks, especially occupational stress and burnouts. Mental health becomes a critical aspect for occupational safety and health. Therefore, employers aim to improve employees' well-being and safety at the workplace through dedicated health initiatives. Internet-of-things (IoT) technology is increasingly being used for such purposes. However, its implementation in the workplace is accompanied by privacy concerns related to sensitive data collection. In this study, we provide a meta-synthesis of existing IoT solutions for supporting employees' mental health in office settings. We classify existing studies into use cases with possible implementation options. We also discuss main challenges emerging from privacy concerns along the IoT data lifecycle. We emphasize the opportunity for the connected workplace to improve occupational health in the future workplace,
