Young motorcyclists are exposed to high noise exposure which can affect their cognitive function. This study was designed to evaluate the cognitive function of undergraduate University students (aged: 19-25) which ride a motorcycle as a primary mode of transportation. Total of 60 motorcyclists participated which were divided into two groups: an experimental group which performed neuropsychological battery test under motorcycle noise (≤90 dBA) and control group under controlled laboratory noise (≤65 dBA). The result showed significantly better cognitive performance (p < 0.05) of a control group. The results demonstrated that motorcycle noise significantly decreased the cognitive performance of the experimental group (p < 0.05).Keywords: Motorcycle noise; Motorcyclists; Neuropsychological assessment; Reaction-timeeISSN 2398-4295 © 2019.

Saliva cortisol response was investigated from the motorcycling exposure for approximately 50 minutes between low and high noise-sensitive (Weinstein Noise Sensitivity Scale) young riders (19-25 years). The results showed significant difference (p < 0.05) in salivary cortisol concentrations in High-Noise Sensitive group (n=27). Significant gender differences were found (p < 0.05) among the Low-Noise sensitive group (n=30), after ride. Cross-analysis between groups was significant (p < 0.05) for before ride cortisol levels of Low-Noise sensitive group. This study suggests that subjective noise sensitivity plays a vital role in increased cortisol level among noise sensitive riders.Keywords: Noise; Salivary cortisol; Noise sensitivity; Motorcycle.eISSN 2398-4279 © 2018.
