Assessment on Occupational Noise Exposure Among Workers in Aluminium Manufacturing Company in Klang, Selangor

Abstract

Noise is a major environmental hazard that can have a significant impact on human health and well-being. Numerous health issues can be caused by prolonged exposure to excessive noise levels including hearing loss, tinnitus, and cardiovascular disease. Exposure to excessive noise can cause hearing loss and that noise is considered a severe danger to human well-being. Aluminium manufacturing involves various machines that produce high levels of noise. This study is aimed to determine the percentage of self-report noise induced hearing loss (NIHL), evaluate the noise exposure level in the company and create noise mapping to identify the high-risk work areas.
