For noise levels up to 101 dBA, these cap-mount earmuffs provide effective hearing protection.
? Cap-mounted design allows for easy use with most hard hats
? Liquid/foam filled ear cushions
? Color-coding for compliance sighting
? Noise Reduction Rating (NRR)*: 24 dB. 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.
