3M Explains the Effect of Eyeglasses on the Fit and Attenuation of Earmuffs

Wearing eyeglasses and earmuffs at the same time can give rise to noise attenuation issues.

To maintain attenuation as close as possible to the rated SLC80 value during testing to Australian Standard AS/NZS1270 standards, the eyeglass arms or temples should fit close to the side of the head and be as thin as is practically possible so that they do not affect the ability of the cushions to seal around the ear.  

The loss in attenuation that temples create with cushions in good condition is generally in the range of 3 - 7 dB.

The noise attenuation effect varies among earmuffs and also depends upon the style and fit of the eyeglasses on the wearer.

In addition to its Peltor and 3M range of earmuffs and earplugs, 3M Occupational Health and Environmental Safety offers an extensive range of safety glasses and goggles, many of which are compatible with earmuffs and other hearing protection devices.
