Abstract: The aim of the study was to determine the effects of noise on the operators’ productivity and performance at Malaysian automotive industry. One automotive assembly factory had been chosen as a subject for the study. The subjects were workers at the assembly section of the factory. The environment examined was the sound pressure level (dBA) of the surrounding workstation area. One set of representative data, which is the sound pressure level (dBA) and production rate were collected during the study. The production rate data were collected through observations and survey questionnaires while the sound pressure level (dBA) was measured using Quest Hand Held Pro Sound Level Meter. The correlation and linear regression analysis were conducted in order to obtain the relationship between the effects of sound pressure level (dBA) to the worker productivity and performance. The results from the correlation analysis revealed there is a weak negative relationship between the sound pressure level (dBA) and the productivity of the workers. The linear regression analysis further reveals that there is a linear equation model with negative slope to describe the relationship of sound pressure level (dBA) and workers productivity for the assembly section involved.
