Traveling on a motorbike beyond 50mph, can expose the driver to up to 90dB of noise under the helmet. The maximum recommended exposure limit at this level is 2.5-3 hours at a time. While slow city traffic might be more manageable, it’s more the day-in/day-out exposure, as well as longer travels on open roads that do the damage. Courier or no courier, all bikers can be affected.
