Why Use Hearing Protection?

Hearing loss due to noise is almost entirely preventable by judicious use of hearing protection. To find out which hearing protection products are best for you, try different devices from the wide variety available today. Be sure to carefully read the instructions — hearing protection must fit properly and be worn correctly to do the job.

Hearing protector effectiveness is specified by a Noise Reduction Rating (NRR), typically ranging from 15 to 35 decibels. In practice, the protection that normally can be achieved is about 10 to 20 decibels. The more carefully you fit and wear hearing protectors, the higher your protection will be.
