Introduction Noise-induced hearing loss (NIHL) is a serious problem for workers and therefore for businesses. The hearing conservation program (HCP) is a set of coordinated measures to prevent the development or evolution of occupational hearing loss, which involves a continuous and dynamic process of implementation of hearing conservation routines through anticipation, recognition, evaluation, and subsequent control of the occurrence of existing environmental risks or of those that may exist in the workplace and lead to workers' hearing damage. Objective The aim of this study was to evaluate the effectiveness of the HCP in preventing further hearing loss in workers with audiograms suggestive of NIHL. The audiometric tests and medical records of 28 furniture company workers exposed to noise were reviewed and monitored for 2 years. Methods This retrospective, cross-sectional study examined five audiometric tests in the medical records (on admission and every semester) of 28 workers in a furniture company (totaling 140 audiometric exams) following the introduction of the HCP. Results Data analysis showed no differences between the audiometric tests conducted on admission and those performed every semester. Conclusions The HCP implemented was effective in preventing the worsening of hearing loss in workers already with NIHL when exposed to occupational noise. Therefore, such a measure could be useful for the employment of workers with hearing loss in job sectors that have noise exposure.
引言 噪声性听力损失（NIHL）对工人乃至企业来说都是一个严重问题。听力保护计划（HCP）是一套旨在预防职业性听力损失发展或恶化的协调措施，它涉及一个持续且动态的过程，即通过对工作场所中已存在或可能存在的会导致工人听力受损的环境风险进行预判、识别、评估及后续控制，来实施听力保护常规措施。目的 本研究旨在评估听力保护计划在预防听力图提示有噪声性听力损失的工人听力进一步下降方面的有效性。对28名接触噪声的家具公司工人的听力测试和病历进行了回顾，并对其进行了为期2年的监测。方法 这项回顾性横断面研究在听力保护计划实施后，检查了一家家具公司28名工人（共140次听力测试）病历中的五次听力测试（入职时和每学期一次）。结果 数据分析表明，入职时进行的听力测试与每学期进行的听力测试之间没有差异。结论 实施的听力保护计划在预防已患有噪声性听力损失的工人在接触职业噪声时听力损失恶化方面是有效的。因此，这样的措施对于在有噪声暴露的工作岗位上雇佣听力损失工人可能是有用的。
