Hearing Protection
A range of hearing protection with different levels of sounds attenuation, to adapt to various working environments giving the correct protection from dangerous noise, without isolating the worker.
The performance of the hearing protector (its attenuation level) must be adapted to the risk assessment of the workplace. It should bring the noise level to a level that is not harmful to health, while avoiding over-protection which would cut the operator from his or her environment (warnings, communication etc).
