Abstract

Introduction Learning process of automotive vocational high school students has a large portion in using practicum machines, that can raises noise and threatens the hearing of students. Noise causes hearing loss known as noice induce hearing loss (NIHL), and it can be permanent, so prevention efforts are very important. Methods This study was included in observational analytic research with cross sectional study design and was held at ORL-HNS OPD of Neurotology Division, Installation of Clinical Pathology and Central Installation of Biomaterial Bank at Soetomo General Hospital Surabaya in May 2018. Results The range of age population is 17-20 years, The measurement of ROS levels in plasma with NIHL obtained a minimum value of 3.00 ng/ml and a maximum value of 9.70 ng/ml with a mean (SD) of 4.4894 ng/ml (1.7148). The ROS level in plasma without NIHL obtained a minimum value of 0.86 ng/ml and a maximum value of 2.81 ng/ml with a mean (SD) of 2.1047 ng/ml (0.5790). The Mann-Whitney test showed significant results between ROS levels in plasma and NIHL (p <0.05). Conclusion There is a corellation between ROS levels in plasma and NIHL in automotive engineering vocational school students. ROS levels in students with NIHL were higher than ROS levels in students without NIHL.
