Ear muffs
The difference between protection and dedication. What’s really protecting your workers from noise-induced hearing loss? Years of commitment to hearing protection by the dedicated scientists and researchers from 3M Hearing Protection. With a full line of ear muffs, you can rest easy knowing that your workforce — and your business — is protected by 3M science. And that makes a world of difference.
Situational awareness, enhanced attention
Focus on your work and communicate with your colleagues in noisy environments, with the help of 3M™ Peltor™ Communication Headsets.

Ear muffs are offered in various positions: over the head, behind the head, and cap attached which may affect the NRR and CSA class.
3M™ Peltor™ X Series Ear Muffs
Applied to moderate-to-high industrial noises, lightweight 3M™ X-Series Ear Muffs are the perfect match. With a designed spacer, specially formulated foam liners, and innovative ear cushions, our science can help you to improve attenuation.

- For eight-hour TWA noise exposures up to 95 dBA
-
- For eight-hour TWA noise exposures up to 98 dBA
-
- For eight-hour TWA noise exposures up to 101 dBA
-
- Unique double-shell cup design provides high attenuation for eight-hour TWA noise exposures up to 105 dBA
3M™ Peltor™ Specialty Series Ear Muffs
You want hearing protection that matches the versatile jobs you do. Whether you need low-profile muffs to accommodate a helmet or the option for a push button to briefly boost outside sounds, the Specialty Series helps keep you protected while suiting the unique needs of your job.

- A low-profile neckband design for use with 3M™ Welding Helmets. Soft earcup surface helps minimize scratch sound transmission when welding helmet is worn
Safety ratings
Hearing Protection Devices (HPDs) are selected based on the noise exposure at the workplace. Other important considerations are comfort, fit, ability to communicate, compatibility with other personal protective equipment and the workplace environment. The following methods can be used to select the most appropriate HPD: Noise Reduction Rating (NRR), CSA Class, Octave Band or Fit Testing.
-
Noise Reduction Rating
The NRR is a single number method that describes the overall sound level reduction across frequencies (attenuation) of a HPD in decibels (dB) based on a laboratory test. Since the NRR is a laboratory test it is recognized that it may overestimate the protection achieved by users in their workplace settings. Therefore, it is recommended that the NRR be derated in order to better estimate workplace protection. The NRR derating scheme can be found in CSA Z94.2-14 Hearing Protection Devices Standards, Table 2: Effective rating calculations for the NRR.
-
CSA Class
The CSA Class describes the sound level reduction (attenuation) of a HPD using the letters A, B, or C which pre-assigns the HPD according to defined attenuation ranges. The CSA Class can be found in CSA Z94.2-14 Hearing Protection Devices Standards, Table 3: Assignment of class based on the octave band attenuation values measured according to ANSI S3.19. It is important to note that the Class pertains only to level of attenuation of the HPD, not to any of its other characteristics.
