Measurements taken by the Occupational Health and Safety Service show that at a speed of 50mph the sound level under the helmet is over 90 decibels. Speed has a significant effect on the sound level the rider is exposed too. For each 12mph increase in speed, the intensity of the sound is doubled. This means that at just over 60mph the rider is exposed to approximately the same level as a circular saw operator who would not be allowed by law to operate the equipment without the mandatory use of hearing protection.

Using the government noise regulation figures implemented for the workplace, the safe exposure time relative to riding a motorcycle at certain speeds are as follows:

All of the noise levels indicated above exceed the point at which hearing protection MUST be worn in a working environment.

Noise induced hearing loss is permanent and irreversible. Adequate protection of the hearing mechanism is as important as the use of a helmet and leathers. Conventional foam and wax earplugs can be a solution but are often uncomfortable to wear and isolate the rider from his surroundings too much. Alternatively if not inserted properly they provide little or no protection.

Custom made hearing protection provides an individual and unique fit for the user allowing guaranteed levels of protection and comfort.
