Abstract

This study evaluates the attenuation of the sound when using a motorcycle helmet, and measures the aerodynamically generated noise inside a helmet when driving. The possibility of detecting certain signals was judged when masking and attenuation effects were taken into consideration. It concludes that the risk of hearing damage is very limited, acoustic warning signals are audible only at low speed, the helmets don't put the wearers at a disadvantage compared with non-helmet situations, and further development of the aerodynamic design of motorcycle helmets is considered essential.
