Relationship between Compliance with Hearing Protection Use and Audiometry Results in Workers Exposed to High Noise Levels

Background: Noise exposure in the work environment is one of the main risk factors for hearing loss in industrial workers, especially when the noise level exceeds 85 dB. The use of hearing protection devices (HPD) is an important preventive measure, but their effectiveness is highly dependent on the level of compliance with their use by workers. Objective: This study aims to determine the relationship between HPD compliance and audiometry results in workers at PT Elangperdana. Methods: This study used a quantitative approach with a cross-sectional design. A sample of 204 workers from the production department of PT Elangperdana who were exposed to noise above 85 dB was selected using a total sampling technique. Data were collected through noise intensity measurements using a sound level meter, questionnaires related to compliance with the use of HPD, and the latest audiometry test results. Data analysis was performed using the chi-square test with the help of SPSS. Results: The results of the data analysis showed that there was a significant relationship between noise exposure above 85 dB and compliance with the use of HPD on audiometry results (p <0.001). In addition, workers with working hours of more than 8 hours and working periods of more than 5 years have a higher prevalence of hearing loss. Conclusion: Excessive noise exposure in the work environment adversely affects hearing health, and compliance with using HPD is very important to prevent hearing loss.
