This paper presents results of an ergonomic study pertaining to the effect of noise on industrial workers in Malaysia. Three different industries selected for the study were rubber product manufacturing, metal stamping, publication and printing. A questionnaire consisting of 37 questions, covering all possible reported effects of noise on humans, was prepared and served to a total of 120 workers at the above mentioned industries. Responses from the workers were collected for analysis. A Chi-Square test was used to determine whether the effects of noise were statistically significant or not. It is found from the results of the survey, at a level of significance, α = 0.05, physiological, hearing loss, auditory, and sleep disturbances effects of noise are statistically significant. However, psychological effect of noise is found to be non-significant.

    ABSTRACT: The extent of noise in five printing companies in Novi Sad, Serbia, was determined using TES-1358A Sound Analyzer with RS-232 Interface. The data on equivalent A-level (dBA), as well as, maximum and minimum sound pressure levels were collected. It was found that folders and offset printing units are the predominant noise sources, with the average L eq levels of 87.66 and 82.7 dBA, respectively. Forty percent of the machines produced noise levels above the limiting threshold level of 85 dBA, allowed by law. The noise in all printing companies was dominated by higher frequency noise, and the maximum level mostly appeared at 4,000 Hz. For offset printing machines and folders, the means of L eq levels exceeded the permissible levels given by NR-80 curve at higher frequencies. There are no published studies of occupational noise and hearing impairment of workers exposed to hazardous noise in printing industry in Serbia. More extensive studies are needed to determine the exact impact of noise on the workers. Technical and organizational measures in order to control noise and prevent noise exposure, and general hearing conservation program to protect workers, should be introduced in printing industry.

    ABSTRACT: The purpose of this study was to assess the relationship between psychological stresses and noise stresses on printery workers in Tehran, Iran. Hence, 267 workers were randomly selected. The Leq and Lmax were measured and the psychological stresses such as depression, anxiety, aggression and job satisfaction were also studied by the relevant questionnaires. The data were statistically analyzed by Pearson correlation test. The results demonstrated that there was no significant statistical relationship between noise and psychological stresses. In addition, by using Spearman regression method, the influence of variables such as age, gender and job history on psychological stresses caused by Leq and Lmax was studied and the results only revealed that the aggression caused by Leq increased in young personnel (P=0.02) as well as, anxiety caused by Lmax increased accompanied by increasing the job history and age of the workers (P=0.002 and P=0.007). Therefore, more variables must be taken into consideration to judge about noise induced psychological stresses in workplaces
