Abstract
Noise is the insidious of all industrial pollutants, involving every industry and causing severe hearing loss in every country in the world. Occupational hearing loss includes acoustic traumatic injury and noise-induced hearing loss (NIHL), and can be defined as a partial or complete hearing loss in one or both ears as the result of one’s employment. NIHL is an important public health priority because as populations live longer and industrialization spreads. Hearing loss is the third most common disease in the adult population, ranked after cardiovascular diseases and hypertension. It has been estimated that worldwide, as much as 500 million individuals might be at the risk of developing noise-induced hearing loss (NIHL). An evaluative approach pre experimental research design was conducted among 60 automobile workers. Convenient sampling technique was used to select samples. Structured interview was used to collect demographic data. Pre-test was conducted to assess the knowledge on automobile workers followed by administration of instructional module. After 7 days post test was conducted by using same questionnaire. The study finding revealed that after the administration of instructional module among automobile workers. There was statistically significant difference between pre-test and post-test knowledge scores and the hypothesis was accepted. The calculated paired‘t’ test value of t=15.1594 was found to be statistically highly significant at (P<0.001). This clearly interferes there is significantly improvement in the post-test level of knowledge regarding prevention of hearing loss among automobile workers.
