Abstract

The purpose of the present study involved the investigation of the significance of wind noise as a contributing factor toward temporary threshold shifts among a select sample of motorcycle riders. Five normal-hearing, helmeted, female subjects were administered pure-tone air-conduction hearing tests immediately before and within 2 minutes after exposure to three noise-related aspects of motorcycle riding. The amount of hearing loss present at 3k, 4k and 6k Hz after each 20 minute exposure condition was recorded as the TTS for that subject. The three conditions consisted of motorcycle noise only, wind noise only and motorcycle and wind noise combined. A statistical analysis of the data revealed that motorcycle noise alone produced significantly less TTS than the wind only or the wind and motorcycle noise. These findings support the hypothesis that wind noise is a significant factor in the production of TTS and possible noise-induced hearing loss among motorcycle riders.
