Earplugs
Young workers don’t want what was. They want what’s next.
Bright colors. Different shapes. Easy-use features. Today’s
younger workforce can be a challenging group to get to wear
hearing protection. Simply put, they don’t want “yesterday’s
plugs. They want new.

Earmuffs
Choosing the right earmuff for workers is a critical decision.
A muff with too little attenuation leaves workers vulnerable
to noise induced hearing damage. One with too high of a
protection level can “overprotect” and make it difficult to hear
voices, signals, and make a worker feel isolated. Now theres
an easy solution. Just match the numbers to the noise levels.

Research suggests that many users will receive less noise reduction than indicated by
the NRR due to variation in earplug fit and wearing time. It is recommended that the NRR
be reduced by 50% for estimating the average amount of noise reduction provided.
