A Controlled Study on Young Motorcyclist’s Cognitive Function

Abstract

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.
