From the Manufacturer:

3M™ Peltor™ Optime™ 105 Behind-The-Head Earmuffs are recommended for time-weighted average (TWA) noise exposures up to 105 dBA. The behind-the-head design allows for easy use with hard hats. The wide foam-filled cushions help create a comfortable noise-blocking seal. These comfort features may encourage a higher rate of hearing protection compliance among workers who require hearing protection. Recommended applications for these earmuffs include chipping, chiseling, drilling, furnace operations, grinding, heavy equipment operations, machining, pouring/casting, power fastening, riveting, sanding, sawing, and welding. These behind-the-head earmuffs are commonly used in the following industries: construction, general manufacturing, mining, oil and gas, and transportation.

For noise exposures up to 105 dBA, these lightweight and comfortable Optime 105 earmuffs have a Noise Reduction Rating (NRR) of 29 dB. The proprietary Twin-Cup™ design features double-shell technology to provide effective hearing protection.

Exposure to loud noises can adversely affect the ability to hear over time. Wearing proper hearing protection devices can help in reducing the harmful effects of noise. Sound levels are expressed in decibels, often abbreviated as dB. Higher decibel numbers indicate louder sounds. Typical decibel levels associated with common sounds include: outdoors with no people or traffic 20 dB, normal conversation 60 dB, power lawn mower 90 dB, chain saw 110 dB, and 12-gauge shotgun 165 dB. The hearing protector NRR can be used to evaluate different hearing protection options. However, the actual level of protection varies depending on fit, wearing time and other factors.

*U.S. EPA specifies the NRR as the measure of hearing protector noise reduction. However, 3M makes no warranties as to the suitability of the NRR for this purpose. 3M strongly recommends personal fit testing of hearing protectors. Research suggests that users may receive less noise reduction than indicated by the attenuation label value(s) on the packaging due to variation in fit, fitting skill, and motivation of the user. Refer to applicable regulations or guidance on how to adjust attenuation label values. It is recommended that the NRR be reduced by 50% to better estimate typical protection.
