Noise-Induced Cortisol Assessment among Young Motorcyclist: A field study

Abstract

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.
