Ear Plugs (disposable) If you do prefer earplugs for your protection, be sure to take these steps to get their full benefit: In a noisy environment, keep your plugs in place. Always follow the guidelines from the

If a 10-decibel reduction in your ability to hear is detected at the 2,000, 3,000 or 4,000 Hertz frequencies, you will be notified. This kind of hearing change is known as a Standard Threshold Shift. It means that a sound has to be 10 decibels louder for you to hear it than was necessary in previous years. If the test shows you have experienced this

kind of hearing loss, you may be ask to take the test again. Hearing Health Tips Noise can damage hearing when it averages 90 decibels or more for an eight-hour period. Be particularly aware of:

High frequency sounds. Loud sounds. Duration you are exposed to harmful sound. Take Care Your life would not be the same without the ability to hear.

Hearing is irreplaceable. Do everything you can to preserve it before its to late.
