Abstract Background The prevalence of hearing impairment among palm oil mill workers underscores the urgent need for comprehensive investigation and intervention. This cross-sectional study, conducted in the East Coast region of Sabah, Malaysia, delved into the factors contributing to this concerning trend. Objectives: This aims to explore the multifaceted aspects of hearing impairment among palm oil mill workers, emphasizing the importance of understanding noise exposure and hearing comprehencive program (HCP). Methods: A total of 262 high-noise-level operators from five selected Palm Oil Mills participated voluntarily. The methode of the study included hearing tests, analyzing noise reports, and using surveys. Result: 12.97% of participants experienced hearing impairment, with Palm Oil Mill A registering the highest rate at 47.82%, indicating significant variations across mills and job roles. Specifically, Engine Drivers had the highest prevalence of hearing impairment, at 26.67%. Additionally, participants with No Education or UPSR/Primary School education levels exhibited the highest rates of hearing impairment, at 16.98% and 16.95% respectively. The study also found a weak but significant positive correlation (r=0.416) between noise exposure and audiometry frequency. In terms of compliance with the HPC, Palm Oil Mill E (POM E) and Palm Oil Mill A (POM A) received low ratings, indicating poor compliance. These mills also had the highest noise levels, exceeding the permissible exposure limit (PEL). On the other hand, POM C, POM B, and POM D showed good compliance with the program, possibly due to effective hearing protection measures already in place. Conclusions: This study underscores the critical need for enhanced regulations, better control measures, and increased awareness to mitigate hearing impairment risks among palm oil mill workers. Future research should delve deeper into factors influencing hearing impairment and evaluate the effectiveness of existing HCPs. Comprehensive studies focusing on HPD practices and awareness programs are essential to inform targeted interventions and enhance workplace safety in the palm oil industry.
