Abstract

Background: Occupational noise is considered a factor contributing to acquired hearing loss (HL) in adults. Frequent noise exposure can cause cochlear damage, leading to sensorineural HL, tinnitus, vertigo, and other non auditory effects as well. Although it is well known that liquefied petroleum gas (LPG) plants in India have become a workplace source for occupational noise pollution exposure, there are not many studies that probe into the auditory effects of workplace noise in LPG plants.

Aim: The study aims to document HL and self reported otological symptoms in employees with occupational noise exposure at a typical LPG plant in a suburban location in India. 53 employees who reported workplace noise exposure were assessed for HL and self reported auditory symptoms.

Method: Self reported symptoms were collected using a custom made case history questionnaire, and auditory sensitivity was measured using air conduction audiometers.

Results: Among the 53 participants, 27 tested positive for HL. A mild degree of HL was frequently observed, followed by a moderate and severe degree of HL. In the self reported otological complaints reported by 31 participants, HL and aural fullness were the most commonly reported auditory symptoms. Additionally, the use of ear protection devices and hearing conservation practices among the participants were poor.

Conclusion: Hearing loss and self-reported auditory symptoms were present in the study group indicating the effect of occupational noise in the auditory system.

关于一家小型液化石油气厂工人自述听觉症状和听力损失的探索性研究。
背景:职业噪声被认为是导致成人后天性听力损失(HL)的一个因素。经常接触噪声会造成耳蜗损伤,导致感音神经性听力损失、耳鸣、眩晕以及其他非听觉影响。尽管众所周知,印度的液化石油气(LPG)工厂已成为职业噪声污染的工作场所源,但探究液化石油气工厂工作场所噪声对听觉影响的研究并不多。对 53 名报告暴露于工作场所噪声的员工进行了 HL 和自我报告的听觉症状评估:方法:使用定制的病史问卷收集自我报告的症状,并使用气导听力计测量听觉敏感性:结果:在 53 名参与者中,27 人的 HL 检测呈阳性。结果:在 53 名参与者中,有 27 人的 HL 检测结果呈阳性,其中轻度 HL 患者居多,其次是中度和重度 HL 患者。在 31 名参与者自述的耳科主诉中,HL 和听力饱胀是最常见的听力症状。此外,参与者使用护耳设备和听力保护措施的情况较差:结论:研究组中存在听力损失和自我报告的听觉症状,这表明职业噪声对听觉系统有影响。
