引言：噪音是目前在经济活动的各个部门对健康有害的因素之一。听力损失和耳鸣是职业性噪声暴露工人最常见的主诉之一。目的：分析听力正常工人在职业性噪声暴露后的听力和耳鸣情况。方法：在冶金行业进行横断面分析试验，对听力正常工人进行回顾性分析、测听和耳声发射。结果：观察到耳声发射失败（40%）和耳鸣（66.6%）的高患病率。在振幅和信噪比方面，声音的频率越高，结果越差。尽管在正常范围内测听，结果表明，工人遭受的影响，暴露和揭示失败的耳声发射和耳鸣之间的关联，在这一人群（X2 = 6，732）。结论：它的结论是，失败的DPOAE和耳鸣的听力损伤的正常听力工人的预测。
INTRODUCTION: Noise is one of the harmful agents to health that is present in the various branches of economic activity. Hearing loss and tinnitus are among the most frequently reported complaints by workers exposed to occupational noise.OBJECTIVE: To analyze the hearing and tinnitus in normal-hearing workers exposed to occupational noise.METHODS: This is a cross-sectional analytical trial in metallurgical industries, in which we evaluated normal-hearing workers through anamnesis, audiometry and otoacoustic emissions.RESULTS: It was observed high prevalence of failure of otoacoustic emissions (40%) and tinnitus (66.6%). Both in the amplitude and in the signal-to-noise ratio, the higher is the frequency of the sound, the worse the results. Despite having audiometry within normal limits, the results indicate that workers are suffering the effects of exposure and reveals association between failure of otoacoustic emissions and tinnitus in this population (X2 = 6,732).CONCLUSION: It is concluded that failures in DPOAE and tinnitus are predictors of hearing damage in normal-hearing workers.
