IMPORTANT USER INFORMATION
Wearing an effective hearing protector 100% of the time is the only reliable
way to protect your hearing.
If you spend time in any environment where the A-weighted sound pressure level
exceeds 85 dB you should protect your hearing, because otherwise the hearing
cells deep in your ears could suffer damage that will never heal. If you remove
your hearing protector for just a short period of time you expose yourself to the
risk of hearing damage.
A comfortable hearing protector that is designed to cope with the noise level
you are exposed to is the best way of ensuring that you will wear your hearing
protector all the time, and therefore gives you the most reliable protection from
hearing damage.
