An Exploratory Study on Self-Reported Auditory Symptoms and Hearing Loss among Workers in a Small-Scale LPG Plant.

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.
