A motorcycle helmet can keep your brains intact in a crash, but your skid lid may hurt your hearing, a recent university study says.
Almost two years ago, researchers from the University of Bath and Bath Spa University started studying helmet-caused wind noise, which they said exceeded legal limits for workplace noise.
Their results weren’t exactly encouraging. Science Daily says the researchers used microphones fitted inside helmets to find that a considerable amount of noise was generated around by air rushing a helmet’s chinbar area, as well as underneath the helmet. The increased noise level was a problem even at legal highway speeds.
They’re continuing the research to determine how wind speed and helmet angle affect the noise volume. They hope their research will be used some day to build quieter motorcycle helmets, but until then, you might want to keep packing ear plugs on road trips.
