Examination of audiologic findings and noise sensitivity in motorcycle couriers

This study evaluated peripheral hearing and noise sensitivity among motorcycle couriers in Istanbul. Participants comprised 31 couriers (29 males, 2 females; age: 28.51 ± 6.23) and 30 controls (27 males, 3 females; age: 27.03 ± 4.20). Assessment included Weinstein's Noise Sensitivity Scale, tympanometry, pure tone audiometry, and otoacoustic emissions. Couriers demonstrated significantly elevated hearing thresholds in the right ear at 500 Hz (p = 0.017), 1,000 Hz (p < 0.001), 2,000 Hz (p = 0.004), 4,000 Hz (p = 0.001), 6,000 Hz (p = 0.002), and 8,000 Hz (p < 0.001), and in the left ear at 4,000 Hz (p = 0.010) and 8,000 Hz (p = 0.039). Noise sensitivity scores were significantly higher (p = 0.031). Motorcycle couriers represent an occupational group vulnerable to hearing loss and heightened noise sensitivity. Protective measures should encompass environmental noise mitigation, speed limit regulation, and helmet redesign incorporating ear protection to promote hearing conservation and improve overall well-being.
