Premolded Plugs – Plugs made of soft flexible material preformed to fit the ear. Must be
fitted (sized) for each ear. These plugs are designed for reuse and must be washed after
each use. They are good to use in cases when hearing protection is used on a regular basis.
Earmuffs – Adjustable headband with soft cups and cushions that seal around the ear.
Plugs may be worn under muffs for additional protection. Muffs may be more comfortable to
wear over a longer period than plugs, but should not be worn with eyeglasses or any other
obstruction that will reduce their effectiveness.
Note: It is important to follow the manufacturer's instructions on proper selection, use, care and
limitations of the hearing protection device.
How noise can hurt you:
Too much exposure to loud noise can result in stress, from constantly straining to listen and be heard.
Noise can cause you to miss important safety instructions.
Prolonged exposure to loud noise can result in permanent hearing loss.
Even if you are exposed to loud noise for a short time, you may lose your hearing.
How to tell if noise is hurting you:
You may have a problem if you hear ringing or other noises in your ears, have a hard time hearing
people when they talk to you, or are unable to hear high pitched or soft sounds.
If you experience any of these problems, tell your supervisor. You may need to have your hearing
tested.
Noise is defined as sounds people prefer not to hear. Noise is especially dangerous in the workplace
because it interferes with communication and disrupts concentration. Sound is measured in decibels.
Noise that is 85 decibels or greater for more that eight hours a day, can affect your hearing.
