•
Wearing custom earplugs for long periods of time may require an adjustment
period of a week or more.
•
Begin by wearing earplugs for one hour at a time for the first several days.
•
Once acclimated to the earplugs, start wearing them for two or more hours until
they can be worn for an entire shift. Do not risk exposure to noise without wearing
hearing protection.
Caution:
For noise environments dominated by frequencies below 500 Hz, the C-weighted
environmental noise level should be used.
Although hearing protectors can be recommended for protection against the harmful
effects of impulsive noise, the NRR is based on the attenuation of continuous noise
and may not be an accurate indicator of the protection attainable against impulsive
noise such as gunfire.
