Abstract

This study investigated the association between occupational noise exposure levels (ONEL) and auditory health among traffic enforcers in Cebu City, Philippines. Using a descriptive-correlational research design, the study involved 56 traffic enforcers who were categorized based on high or low levels of noise exposure. Data were gathered through structured health history questionnaires and audiometric testing via Pure Tone Audiometry (PTA). Results revealed that ONEL had a statistically significant association with hearing thresholds at 8000 Hz (p = 0.027), indicating high-frequency hearing loss among those exposed to elevated noise levels. However, no significant associations were observed at lower frequencies. Notably, age (p = 0.013 right ear; p = 0.012 left ear) and self-reported hearing-related health outcomes (p = 0.015 right ear; p = 0.011 left ear) were significantly associated with PTA results, suggesting that hearing loss may also be influenced by age-related factors and underlying health conditions. Other variables—including smoking status, alcohol use, and exposure to recreational noise—showed no significant correlation with either ONEL or hearing thresholds. These findings underscore the multifactorial nature of occupational hearing loss and emphasize the need for targeted health surveillance, regular audiometric screening, and preventive hearing conservation programs tailored to the specific risks faced by traffic enforcers.
