There are many possibilities for noise exposure in industrial workplaces, including sectors that extensively use heavy machinery in processing each product. Various studies indicate a causal relationship between noise exposure and auditory/nonauditory effects among workers. Noise exposure poses risks to health and workers' hearing acuity and safety. This review paper aims to identify and summarize occupational noise exposure by examining the auditory and nonauditory effects among mill workers. The mills included in the study are palm oil, lumber, textiles, rice, sugarcane, flour, paper, and sawmills. A two-step methodology was used to achieve the aims of this narrative review. The literature search was conducted by gathering PubMed and Google Scholar papers, focusing on occupational noise in different occupational mill environments. Grey's literature was conducted by screening the worldwide national standard for the laws, guidelines, and other related information based on this topic. A total of 22 articles published have been included. The content of each publication was subsequently summarized. Most of the machine areas within the mills emitted high level of noise. The auditory effects of occupational noise exposure among mill workers were noise-induced hearing loss and hearing impairment. Hypertension, stress, communication disturbance, cardiovascular disease, and headache were the nonauditory effects experienced by workers. The recommendations provided in this review for mitigating noise exposure are derived from the hierarchy of control. Overall, most mill workers are exposed to a high noise level exceeding the standard noise exposure limit. Preventive actions should be taken to address and reduce work-related injuries among mill workers worldwide.
在工业工作场所，存在许多噪声暴露的可能性，包括在加工每种产品时广泛使用重型机械的行业。各种研究表明，工人的噪声暴露与听觉/非听觉影响之间存在因果关系。噪声暴露对健康以及工人的听力敏锐度和安全构成风险。这篇综述文章旨在通过研究工厂工人的听觉和非听觉影响来识别和总结职业噪声暴露情况。该研究纳入的工厂有棕榈油厂、木材厂、纺织厂、碾米厂、甘蔗厂、面粉厂、造纸厂和锯木厂。采用了两步法来实现这篇叙述性综述的目标。通过收集来自PubMed和谷歌学术的论文进行文献检索，重点关注不同职业工厂环境中的职业噪声。通过筛选基于该主题的全球各国法律、指南及其他相关信息的国家标准来获取灰色文献。总共纳入了已发表的22篇文章。随后对每篇出版物的内容进行了总结。工厂内的大多数机器区域都发出高强度噪声。工厂工人职业噪声暴露的听觉影响包括噪声性听力损失和听力损伤。高血压、压力、沟通障碍、心血管疾病和头痛是工人经历的非听觉影响。本综述中提出的减轻噪声暴露的建议源自控制层级。总体而言，大多数工厂工人暴露于超过标准噪声暴露限值的高噪声水平。应采取预防措施来解决并减少全球工厂工人与工作相关的伤害。
