Product Description

From the Manufacturer

3M™ Peltor™ Optime™ 98 Over-the-Head- Earmuffs are recommended for TWA noise exposures up to 98 dBA. A stainless steel headband provides consistent force to keep the earcups snugly in place yet with comfortably low pressure. Earcup pivot points tilt for a fit that is customized to each wearer. The wide and liquid/foam filled earmuff cushions fit gently to form a comfortable, noise-blocking seal. Bright yellow earcups provide color-coding for hearing protection compliance sightings. These comfort features may encourage a higher rate of hearing protection compliance among workers who require hearing protection. These earmuffs are commonly used in the following environments: factories, sheet metal works, schools, printing and textile operations, and power equipment.

For noise levels up to 98 dBA, these lightweight and comfortable Optime 98 earmuffs feature low-profile ear cups that fit well with most helmets, eyewear, and other safety equipment. The TWA (Time Weighted Average) noise level indicates a worker's daily exposure to occupational noise over an 8 hour day, considering both the average level of noise and the time spent in each area. This measurement is used by OSHA in assessing noise exposure and determining appropriate action.

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. Sounds 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.
