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.
消防员工作的环境中充斥着警笛和应急警报等噪声，这可能会对消防员的表现产生负面影响，进一步构成安全风险。本研究旨在探讨警笛噪声暴露与心理健康障碍之间的关系。为此，本研究首次使用贝叶斯网络模型来关注消防员的认知功能。这项病例对照研究共纳入了 92 名消防员，于 2023 年开展。研究根据消防员的警笛噪声暴露水平，将参与者分为病例组和对照组。噪声暴露最初根据 ISO 9612 标准进行测量。问卷调查涵盖了参与者的人口统计学信息、抑郁、焦虑和压力量表、Buss-Perry 攻击问卷和认知失败问卷。本研究采用 GeNIe 学术软件版本 2.3 进行贝叶斯网络分析。研究结果表明，警笛噪声暴露与抑郁（10%）、压力（14%）、焦虑（13%）和攻击（16%）的概率增加 100%之间存在很强的关联。此外，每个变量——噪声暴露、抑郁、压力、焦虑和攻击，与认知失败的关联程度分别为 8%、28%、8%和 13%。包括噪声暴露、抑郁、焦虑和其他心理健康障碍在内的变量组合，使认知失败的概率增加了 57%。在这些变量中，噪声暴露、抑郁、焦虑和其他心理健康障碍与认知失败的关联度最高，其影响值分别为 0.564。本研究结果表明，警笛噪声暴露及其心理健康障碍会对消防员的认知功能产生影响。研究结果进一步强调了采取措施减轻这些影响的重要性，并需要进一步研究这些措施的有效性。
