Motorcyclists are constantly exposed to high levels of noise caused predominantly by the wind. Measurements made by the Occupational Health & Safety Service of the Dutch Government showed that at 50mph the sound level under the helmet was 90 decibels.
Speed has a significant effect on the sound level and for each 12 mph increase in speed, the intensity of sound is doubled. This means that at just over 60mph, the motorcyclist is exposed to approximately the same sound levels as a circular saw operator who would not be allowed by law to operate this equipment without mandatory use of hearing protection.
Specially developed for the motorcyclists of the dutch police, the Elacin Biopact utilises filters used in other Elacin products, but is made from soft Biosoft material. Together with a crash helmet and communication equipment, Elacin can be worn for a long time with comfort.
