Introduction: textile industry due to noise pollution may cause noise annoyance. Noise annoyance can increase the risk of health problems and sleep disturbance. Thus, this study was conducted to assess the effect of noise annoyance on the sleep disturbance among workers of a textile industry.

Material and Method: All the workers have been divided into four groups according to their noise exposure levels, including Knitting unit, Screw warp and sizing, Control area and Reel Decal. The equivalent A weighted noise levels were measured for each of the study working groups, using ISO 9612 standard method. Information related to the noise annoyance and sleep disturbance were determined by ISO15666 standard and the Epworth Sleepiness Scale, respectively.

Result: Based on the analysis of variance, average noise annoyance caused by occupational groups, age and work experience was different. Two independent samples t-test showed that the education does not significantly associated with noise annoyance. Kruskal - Wallis showed that the mean score of sleep disorder are significant differences between occupational groups. According to this test sleep disorder was significantly associated with the noise annoyance.

Conclusion: In this study, workers with more noise annoyance had more sleep disturbance.

Therefore, in addition to the direct effects of noise on sleep disturbance, it can indirectly exacerbate sleep disturbances.
