Motorcycle helmets may be protecting bikers’ brains but they could also be leaving them vulnerable to hearing loss. Kennedy O Adetifa, M Carley, N Holt and I Walker, researchers in mechanical engineering, management and psychology from the universities of Bath and Bath Spa, Britain, mapped the airflow and noise patterns to find out why.
The distinctive roar of a Harley’s engine is loud, but studies have revealed the biggest source of noise for motorcyclists is actually generated by air whooshing over the riders’ helmets.
