Assessment on Occupational Noise Exposure at Manufacturing Company in Negeri Sembilan

Abstract

Manufacturing of truck and bus bodies involves various work processes and machinery, exposing workers to potentially dangerous high noise levels. Noise emitted from machinery and tools has been linked to several occupational health hazards such as noise-induced hearing loss (NIHL) and tinnitus. The major sources of noise in manufacturing plants are angle grinders, fans, motors, hammers, pumps, cutting saws and drillers. This study aimed to evaluate the noise exposure level in the workstations, assess workers’ daily noise dose, and investigate the relationship between noise exposure level and worker’s daily noise dose.
