Abstract: Background: Hearing impairment is common in adolescents and young adults exposing themselves to loud noise or music through the use of earphones for a long period of time. If the risky patterns of exposure are not being monitored by themselves to the proper extent may lead to noised induced hearing loss in the latter part of their life. Few years ago, the scope of using earphones was less, nowadays the scope of such use has increased to a great extent. Earphones are not only used for listening to recreational music, but also to hear audio-books, online videos, and online educational programs. Methodology: using Pre experimental one group pretest post- test research design. A total of 54 subjects were selected for study by using convenient sampling technique. Self-structured questionnaire was used as a tool. Results: The result of the study revealed that in pretest regarding knowledge of earphone usage 22(40.74%) had inadequate knowledge, 12(22.22%) had adequate knowledge and 10(37.04%) had moderately adequate knowledge with mean and SD of 6.01±18.70 whereas in post-test 49(90.74%) had adequate knowledge and 5(9.26%) had moderately adequate knowledge with mean and SD of 1.54±1.02, mean difference score was 2.69 and the calculated ‘t’ value is t=15.522. In pretest regarding practice of earphone usage 41(75.93%) had inadequate practice, 9(16.66%) had moderately adequate practice and 4(7.41%) had adequate practice with mean and SD of 4.46±1.79 whereas in post-test 25(46.30%) had adequate practice, 24(44.44%) had moderately adequate practice and 5(9.26%) had inadequate practice with mean and SD of 7.00±1.28, mean difference score was 2.53 and the calculated‘t’ value is t=8.846. Conclusion: Study concluded that the Video Assisted Teaching was effective in improving the knowledge and practice regarding health hazards of earphone uses and prevalence of hearing impairment among nursing students
