How to Choose The Best Hearing Protection by Using The Noise Reduction Rating (NRR) | Seton


Prolonged, unprotected exposure to
excessive noise, can cause irreparable hearing damage. It is vital, therefore, that everyone in your facility take
appropriate steps to protect their hearing from
workplace noise. What exactly is considered
excessive noise? Excessive noise has been defined by the
U.S. Environmental Protection Agency as exposure to sound greater than
85 decibels continuously over an 8 hour period. How loud is 85 decibels?
To give you a better idea, here are some samples of fairly
common noises that the EPA would consider excessive All hearing protection devices are individually
rated by how well they reduce noise. This Noise Reduction Rating, or NRR
for short, is clearly visible on the label of every hearing protector
sold in the US today. These earmuffs for example, have an
NRR rating of 30, meaning they will provide 30 decibels
of protection, reducing the sound of a chainsaw from
100 decibels, to a much safer 70 decibels. It is also possible to combine earplugs and
earmuffs for even greater noise protection. Determining the NRR rating for
dual protectors is easy. Just increase the NRR rating of
the higher rated protection device by between 5 and 10 points. In this example, using these disposable
ear plugs with an NRR rating of 33 along with these ear muffs with an
NRR rating of NRR 27 would provide you somewhere between
38 and 43 decibels of noise protection. Seton has the hearing protection
