Tinnitus is a common auditory complaint among individuals exposed to noise.
this paper aims to study the characteristics of tinnitus in workers exposed to noise.
this is a descriptive prospective study.
Fifty-two individuals averaging 29 years of age were enrolled in a hearing loss prevention program at a meat processing plant. The participants were interviewed and had their hearing tested in 2005 and 2006.
seventy-one percent of the participants were found to have normal hearing. Tinnitus was present in 16% of the males and in 9% of the females. Mean noise exposure length was 7 years and noise levels ranged from 86 to 91 dBA (48%). Bilateral tinnitus (46%) of the hissing type (40%) and moderate intensity (49%) was the most prevalent. Symptoms began to be observed within one to five years after initial exposure to noise (67%) and manifested themselves in weekly episodes (41%) that bothered the patients mostly at night (34%). A significant correlation was observed between the frequency of tinnitus episodes and the noise levels to which workers were exposed.
tinnitus should be included in hearing loss prevention programs in order to more comprehensively promote occupational hearing health.
耳鸣是接触噪声的个体中常见的听觉主诉。
本文旨在研究接触噪声的工人的耳鸣特征。
这是一项描述性前瞻性研究。
在一家肉类加工厂的听力损失预防计划中，共有 52 名平均年龄为 29 岁的个体参与了研究。这些参与者在 2005 年和 2006 年接受了访谈和听力测试。
71%的参与者听力正常。16%的男性和 9%的女性患有耳鸣。平均噪声暴露时间为 7 年，噪声水平范围为 86 至 91 dBA（48%）。最常见的是双侧、高音调、持续性耳鸣（46%），强度为中度（49%）。症状在接触噪声后 1 至 5 年内开始出现（67%），每周出现一次（41%），主要在夜间（34%）困扰患者。耳鸣发作频率与工人接触的噪声水平之间存在显著相关性。
应将耳鸣纳入听力损失预防计划中，以更全面地促进职业性听力健康。
