Hearing Protection

• 85 dB(A) is the current maximum sound level,
  to which people may be exposed during a working
  day. To be able to medically guarantee a sound
  level that is harmless to all people, sound must
  be attenuated to a maximum of 75 dB(A).
• It goes without saying that a hearing
  protection program must be based on the principle
  that all people have full protection.

4
NRR Rating

• Noise Reduction Rating - all muffs are assigned
  one
• NRR requirements must be determined by the
  employer through evaluation of the area where
  workers may need hearing protection

5
NRR Rating

• The NRR rating is the stated rating by which the
  protector will decrease the noise reaching the
  workers ears- depends on frequency of noise
• It is possible to have too much hearing protection

Active Listening
Wearers are able to hear important warning
signals, and communicate with those around them
without removing the ear muff. The built in
electronic protection system prevents noise
levels beyond 82Db(A) from going through the
speaker. Built in speakers allow lower level
sounds to enter the muff with a maximum
amplification of 12dB(A). Low/high tone control
allows for alteration of sound for optimum clarity
