Noise exposure of workers assessed according to ISO 9612: 2009. The noise disturbance questionnaire was also completed by participants. Results: The results obtained from the noise exposure measurement showed that the mean of equivalent sound level in employees of administration section was 82.28, in administrative section was 66.52, in supervisory section was 76.43 and in machinery section was 78.45 dB. The results of noise disturbance showed that 25% of workers rated noise in the work environment as very disturbing. The results of regression analysis showed that the type of occupation associated with disturbance of subjects with correlation coefficient of 0.413. Conclusion: According to the results of dosimetry and self-reported disturbance, the noise exposure level and noise disturbance of work environment due to sound sources are high.
