The level of noise intensity and duration exposure of noise can have an impact on hearing loss. Studies on the impact of machine laboratory noise in Vocational Secondary School are still rarely examined and published. The present study was undertaken to know the effect of noise generated by practicum machine on hearing impairment of Vocational School students in engineering using machine in Indonesia. This study was analytical observational which assessed correlation between noise intensity of machine laboratory and its impact of hearing disorder by using cross sectional study. Significance of correlation between noise intensity with hearing disorder in VSS students using machine in Indonesia, with p value : 0.000, OR : 1.84 and 95% CI : 1.653-1.968. Level of noise intensity from machine laboratory impacted hearing disorder in VSS students in Indonesia.
Key words : Noise intensity, machine practice, hearing disorder
