Abstract

Noises in hospitals cause noise-induced hearing loss in the employees. The standard diagnostic is audiometry to determine the hearing level. Distortion product otoacoustic emission (DPOAE)is a potential screening tool for cochlear problems. Noise exposure can be found not only in industrial areas but also in hospitals.This study aims to hear conservations to control the risk factors by doing noise measurement using the sound level meter. The design of this study was an analytic observational study with the cross-sectional design where measurements were made ofintensity and noise dose in 3 installations, namely medical facilities maintenance (MFM), sanitation, and nutrition. Fifty-sixsubjects underwent tympanometry to exclude conductive hearing loss, resulting in a total of 48 subjects who fit the inclusion criteria. The correlation between examination results and age, work station, and working duration were analyzed by usingthe Spearman correlation test (p<0.05). The correlation between noise dose, intensity, and hearing status, however, were analyzed by using Fischer test (p<0.05). The result showed theaverage noise intensity at MFM was 95.83dBA, at the nutrition installation was 99.07dBA, and at the sanitation installation was 105.5dBA. Meanwhile, the average noise dose at MFM was 674.25%, at nutrition was 1632.5%, and at sanitation was 8 977.75%.Abnormal audiometry was 50% and DPOAE refer 77.083%. Thus, it can be argued that there was a significant correlation between the work station and DPOAE (p=0.0184). There wasalso a correlation between noise intensity and hearing loss, whileno significant differenceswere discovered between DPOAE and audiometry.
