For noise levels up to 101 dBA, these over-the-head earmuffs provide effective hearing protection.
– Stainless steel headband distributes weight for low-pressure fit.
– Earcup pivot points that tilt for optimum comfort and efficiency.
– Liquid/foam filled earmuff cushions.
– Color-coding for compliance sighting.
– Noise Reduction Rating (NRR)*: 27dB. CSA Class A.
*The NRR may overestimate the hearing protection provided during typical use. 3M recommends reducing the NRR by 50% for estimating the amount of noise reduction provided.
