The cognitive assessment of young motorcyclists under high-noise exposure has not been investigated previously. Therefore, this study aimed to determine the effects of noise-induced cognitive function and reaction time among undergraduate motorcyclists (aged: 19-25). The study design consisted of experimental (ExG; n=30) and controlled group (CoG; n=30). The ExG performed neuropsychological battery test under motorcycle noise (85-90 dBA) and CoG under controlled laboratory noise (<65 dBA). The result revealed that the CoG had significantly better cognitive performance (p < 0.05) and reaction-time as compared to ExG. The results demonstrated the significant effect of motorcycle noise on decreased cognitive performance and increased reaction time.
