摘要：Motorcycle riders are exposed to excessive turbulent wind noise levels of around 90 dBA at50km/h and up to 116 dBA at 193 km/h. Prolonged exposure can lead to hearing loss, which hasnot been investigated among young riders. A cross-sectional study aimed to examine the prevalenceof Hearing Loss (HL) and Hearing Impairment (HI) among unscreened 174 undergraduateUniversity motorcyclists. Information regarding respondents and hearing status was acquiredthrough structured questionnaire and Pure-Tone Audiometry (PTA), respectively. Participationwas dominated by male riders (66%), age ranging from 19-24 years. The results showed 100%of HL (94.3% bilateral HL, 5.7% non-bilateral HL) and 58.6% of HI (34.5% bilateral HI, 24%non-bilateral HI). Female riders (66.1%) had a slightly higher prevalence of HI than male riders(33.9%). It was found that hearing impairment conditions (normal, bilateral, and non-bilateral HI)was statistically significant with the distance classification (km covered per day), x2 = (2), 2.10,p = 0.034. The classification of hearing impairment based on World Health Organization, the 57%of the participants had mild HI, 2.3% had moderate HI, 0.6% had severe HI, whereas none werefound to be suffering from Profound HI. The prevalence of hearing loss and hearing impairmentwas significantly higher among young motorcyclists, it emphasis the further in-depth investigationfor associated health risks of motorcycling at young age.
