3M 7100315032 Helmet Attached Earmuffs 25-27 Db Nrr

Product Description

The 3M 7100315032 is a helmet-attached earmuff designed for industrial hearing protection in high-noise work environments. With a Noise Reduction Rating (NRR) of 25 to 27 dB, these earmuffs mount directly to compatible hard hats and eliminate the need for a separate headband. The cup is constructed from ABS material with foam and PVC cushioning for a reliable acoustic seal. These earmuffs are designed to meet ANSI/ASA S12.71-2018 standards and are intended for use by safety professionals, industrial workers, and site supervisors operating in regulated noise environments.

These earmuffs are built for helmet-integrated use in industrial and construction settings where hard hat compatibility is required. They are part of the 3M X Series earmuff line and are compatible with H-700 Series Hard Hats and Industrial Safety Helmets. The compact design allows for use in confined workspaces where full-headband earmuffs may be impractical. They are well suited for applications requiring fit-testing capability, including worksites using quantitative hearing protection fit-testing programs.

Key Features

• NRR of 25 to 27 dB provides rated hearing protection in high-noise industrial environments

Installation Notes

Installation is performed by attaching the earmuff cups to the helmet slots on a compatible hard hat before use. No tools are typically required for mounting. Ensure the hard hat model is confirmed compatible before attaching. Workers should verify a proper cup-to-ear seal each time the helmet is donned to maintain the rated NRR.
