  • 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 equipment you need,

  • from disposable and reusable earplugs

  • to earmuffs, as well as earplug dispensers

  • and Hearing Protection Signs and Labels.
