Technical
Datasheet
CAUTION: Research suggests that many users
will receive less noise reduction than indicated
by the NRR due to variation in t, tting skill and
motivation of the user. It is recommended that the
NRR be reduced by 50% to better estimate typical
workplace protection.
The noise reduction may be lower when eyeglass-
es, goggles or respirator straps are worn between
the sealing surface of the earmuff cushions and
the sides of the wearer’s head. For best noise
reduction, select eyeglasses or goggles that have
thin, at temples or straps which will minimize
interference with the seal of the earmuff cushions.
Pull long hair back to the extent possible and
remove other items that may degrade the earmuff
seal such as pencils, hats, jewelry or earbuds. Do
not bend and reshape the headband as this will
cause a loose t and allow sound leakage.

Standard & Approval
In the United States and Canada there is no
approval process for hearing protection. The
standards organizations ANSI and CSA do not
approve or certify hearing protectors. However, a
U.S. EPA requirement (40 CFR 211) species that
hearing protectors sold in the U.S. must be tested
to ANSI S3.19-1974 and labeled with a Noise
Reduction Rating (NRR). 3M Hearing Protectors
have been tested and labeled accordingly.
