“…Since the aim was to study the correlation between variables, the sample size was determined using formula 1 [30]. α, β, and r coefficients were determined by reviewing similar studies and the opinion of the researcher [31,32]. Considering α = 0.05, β = 0.2, and r = 0.29, the sample size was equal to 91.…”

Background: Noise is an important occupational safety and health issue in many workplaces. Noise annoyance is a strong measurable mental response. It is a reaction that a person expresses to the noise exposure. Thus, this study investigates the correlation between noise exposure and its annoyance in terms of mental health components. Materials and Methods: This was a correlational descriptive study conducted on 100 workers. Respondents were recruited by a simple random sampling method. The equivalent sound level (LeqA) was determined using dosimetry. The numerical scale of ISO/TS 15666:2003 was used to measure noise annoyance. Mental health components were determined using the SCL-90 mental health questionnaire. Data analysis was performed in SPSS software (version 22) using Mann-Whitney, Kruskal-Wallis, and correlation tests. Results: The median of mental health and noise annoyance were 38 and 6.5, respectively. A positive correlation was observed between equivalent sound level (LeqA) and noise annoyance score (P<0.001, r=0.92). A significant correlation was found between mental health components (depression, anxiety, self-morbidity, obsession and compulsion, aggression, morbid fear, paranoid thoughts, psychosis, and sensitivity in interpersonal relationships) and equivalent sound level (P<0.001). Also, a significant correlation was observed between noise annoyance score and mental health components (P<0.001). Conclusion:We concluded thatin order to enhance the mental health of employees and increment efficiency and performance, it is recommended that appropriate control methods should be applied.

Introduction: Exposure to vibration and noise has been identified to potentially contribute to work-related fatigue, consequently causing a range of adverse effects on job performance.Method: In this study, a sample of 62 city bus drivers underwent examination to evaluate noise levels through the utilization of a TES dosimeter. Additionally, vibration measurements were conducted using an SV 106 vibration meter. Furthermore, the level of occupational fatigue was determined through the utilization of a Swedish fatigue questionnaire. Results: In the conducted study, it was observed that bus drivers were subjected to an average exposure level of 82.18 dB and 0.99 m/s2 for noise and whole-body vibration, respectively, throughout their work shifts. Additionally, their average job fatigue score was measured to be 26.21 out of a total of 200. To comprehensively evaluate the influence of various factors on (WRF), both single-variable and multi-variable analyses were conducted. The result of the univariate tests exhibited a notable association between job fatigue and the Lon life of the vehicle, the type of car seat (spring or inflatable), as well as the level of exposure to vibration and job satisfaction. Moreover, when considering the influencing factors concurrently in the multivariate test, a significant correlation between occupational fatigue and exposure to vibration, as well as the type of chair, was established. Conclusion: Improving the quality of buses by implementing modernized features that minimize vibrations and reduce noise levels can greatly contribute to mitigating fatigue among urban bus drivers.

Firefighters reside in inherently noisy environments with sirens and emergency alarms. This noise can negatively affect the performance of firefighters and further pose a safety risk. This study investigates the relationship between siren noise exposure and its mental health disorders. In doing so, the study focuses on cognitive function among firefighters, using a Bayesian network model for the first time. This case-control study involved 92 firefighters and was conducted in 2023. Participants were categorized into case and control groups based on their exposure levels to siren noise. Noise exposures were initially measured according to ISO 9612 standards. The questionnaires covered demographic information, scales of their depression, anxiety, and stress, the Buss-Perry aggression questionnaire, and the cognitive failure questionnaire. GeNIe academic software version 2.3 was employed for Bayesian network analysis. The study results indicated a strong association that heightened siren noise exposure with a 100% probability increases depression (10%), stress (14%), anxiety (13%), and aggression (16%). In addition, each variable–noise exposure, depression, stress, anxiety, and aggression was linked to cognitive failure by 8%, 28%, 8%, and 13%, respectively. The combination of variables including noise exposure, depression, anxiety, and other mental health disorders had a 57% increase in cognitive failure. The most influence values were observed between depression and cognitive failures (0.564). The results of this study demonstrated the effect of siren noise exposure and its mental health disorders on cognitive function among firefighters. The results further highlight proper implementation of measures to mitigate these effects, and further required investigation on their effectiveness.
