To determine the level of knowledge of UMSU mechanical engineering students about NIHL and compliancewith the use of protective equipment in the practice of lathes. This study used a descriptive method with cross sectionaldesign with a questionnaire instrument and used a total sampling of all UMSU mechanical engineering students in 2016.This study showed that the level of knowledge of UMSU mechanical engineering students regarding NIHL of wellknowledgeedstudents was 87.5 %, well-knowledgeed 6.66% and poorly-knowledgeed 5.83%. The level of knowledge ofUMSU mechanical engineering students regarding compliance with the use of PPE with good knowledge was 90.8%,knowledgeable was good enough as much as 7.5% and those with less good knowledge were 1.6%.
