Abstract:
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.

Palpation Findings
During a respiratory assessment, palpation can reveal several vital abnormalities:
Perceiving Loudness, Pitch, and Location
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by identifying...
