Description:	Noise exposure become one of the most prevalence industrial problems as a result of large-scale manufacturing and construction. Working under loud noise may have adverse impacts on health measures associated with quality of life (QOL) which can contribute to workplace accidents. Therefore, the objectives of this study are to investigate the occupational noise exposure and the degree of hearing loss (HL) of workers; to determine the QOL, and Knowledge, Attitude and Practice (KAP) related to occupational noise exposure among factory workers; and to determine the relations between occupational noise exposure, degree of HL, QOL and KAP, and check the validation of the model. Eighty-nine workers in a plastic factory in Selangor, Malaysia involved in the study. Noise exposure was monitored in nine areas inside the factory; at six production lines, at crushing department, at packaging department and at officer’s area using sound level meter (SLM). The audiogram data for each of the worker was collected to represent their degree of hearing loss. In addition, two types of questionnaire namely World Health Organization Quality of Life (WHOQOL-BREF) and KAP questionnaires were used to evaluate the QOL and KAP related to occupational noise exposure among workers. The results showed that noise exposure level at the crushing department area was noted higher than other areas at factory, with a maximum value Lmax = 105 dBA and average value LAeq = 100.9 dBA. Meanwhile, the average noise exposure level at all other areas were less than 80 dBA. According to the audiometric data, it shows that 80 workers (89.89%) experienced hearing loss, at least in one audiogram frequency at one side of the ear. Next, the QOL’s mean score for workers was recorded 45.73, which indicates an average of QOL (neither poor nor good). The mean score for KAP was 61.12 (good knowledge), 65.11 (good positive attitude) and 55.41 (average practice) respectively. Furthermore, there was a statistically significant between exposure noise level and overall QOL with p = 0.001 and fair correlation of R = -0.347. Workers knowledge, worker’s attitude and workers practice have a statistically significant with overall QOL with p < 0.05 for all and r equal to 0.347, 0.425 and 0.317, respectively. In conclusion, the quality of life worker was influenced with fair correlation by the noise exposure and their KAP level. The finding in this study can assist employer in providing information for management or manufacturing strategy to ensure their workers welfare always preserved.,Master of Science
