Detachment of crash helmets during motorcycle accidents.

Attenuation of noise by motorcycle safety helmets.

For workers such as police motorcyclists or couriers, traffic and engine noise reaching the ears is an important factor contributing to the overall condition of their work. This noise can be reduced with motorcycle helmets. In this study, insertion loss of motorcycle helmets was measured with the microphone-in-real-ear technique and sound attenuation with the real-ear-at-threshold method. Resul...

Motorcycle helmets--medical costs and the law.

Since 1975, 26 states have repealed or modified their motorcycle (M/C) helmet laws. Louisiana (LA) reinstated the M/C helmet law in 1982. The medical and financial impact of repeal in Kansas (KS), reinstatement in LA (accident, fatality, and critical injury rates) have been studied through 1987. Current FARS data and studies from KS, LA, 10 states and 5 countries are compared and reported. With...

Biomechanics of Solo Motorcycle Accidents

Motorcycles are a luxury in the developed world, where they are used mostly for recreation. Whereas in developing countries, motorcycles are required for utilitarian purposes due to lower prices and greater fuel economy. It is estimated that in 2016 there will be more than 134 million motorcycles worldwide [1], 60-80% of which are in the Asia Pacific and Southern and Eastern Asia regions. In 20...

Economic impact of motorcycle helmets: from impact to discharge.

BACKGROUND The economic impact of helmet use remains controversial. Previous studies of injured motorcyclists suggest a marginal inpatient hospital cost difference between helmeted and unhelmeted riders. The purpose of this study was to expand the economic analysis of motorcycle helmet utilization to the point of injury by including motorcycle crash patients who do not require hospital admissio...
