Relationship of Noise Level to Increased Blood Pressure in Workers at PT X 2025

Abstract

Increased blood pressure is caused by various risk factors, such as noise. Noise is a physical occupational hazard that acts as a stressor, disrupting hearing, sleep, communication, and daily activities, thereby potentially increasing sympathetic nervous system activity. This study aims to investigate the relationship between noise levels and the increase in blood pressure before and after work at PT. Shinko Plantech, a construction and manufacturing company specializing in pipe and forged steel production. This study used cross sectional study. The study subject were workers of PT. Shinko Plantech, selected by stratified random sampling according to inclusion and exclusion criteria. Data were analyzed with chi-square test, using univariate and bivaraite methods, through SPSS application. This study showed 63.3% of workers that were exposed to noise levels ≥ 85 dB, and 66% experienced an increased blood pressure before and after work. Based on analysis, there was a significant association between noise intensity and increased blood pressure (p = 0.048). Other factors, such as age, length of employment, working hours, smoking habits, use of APD (earplug), and body mass index (BMI) were not significant to increased blood pressure before and after work. Noise intensity ≥ 85 dB and increased blood pressure was significantly associated.
