Relationship between Noise Intensity and Psychological Disorders among Workers in the Compressor Machine Division

Abstract

Workers in the compressor machine division experienced the intensity of noise above the threshold value. The negative impacts of noise include discomfort and lack of concentration. This study aims to determine the relationship between noise intensity and psychological disorders among workers in the compressor machine division. This study used a descriptive analytical approach with a cross sectional study design. Data collection method used interview, the instruments used here were questionnaire and sound level meter. The populations in this study were the workers in compressor machine division as many as 39 workers. The sampling used a total sampling technique. The study was conducted in June 2019. Analysis of data used univariate and bivariate analysis with Chi-square test. Based on the results of the study it was obtained that 74.4% of respondents worked in a noisy place and 38.9%). moderate psychological disorders (Chi-square test results obtained p value = 0.005, meaning that there was a relationship between noise intensity and psychological disorders among workers in the compressor machine division. A recommendation for companies is to conduct a hazard control on the machine by means of machine maintenance, replacing machine equipment that produced a high intensity of noise. Furthermore, companies should conduct administrative control by work rotation and regular monitoring of ear muff usage so that workers are safe from the exposureof high intensity of noise. Companies should also onduct machineering control such as providing noise barrier from material capable of dampening the noise source to minimize the effect on the incidence of psychological disorders among workers.
