Clarity Series earmuffs improve worker safety by blocking noise, while voice and signal frequencies can be heard more naturally. Clarity earmuffs provide uniform attenuation that allows speech frequencies to be heard with less distortion – combating worker isolation and overprotection on the job. Plus, Clarity's robust non-deforming dielectric design withstands use and abuse while protecting workers in electrical environments.
The difference between the intensity of "noise" to which the operator is exposed and effectively transmitted to the ear. The attenuation level is expressed in the following the vessel ways:
HML: indicates the attenuation based on the frequency of the noise: high (H), medium (M), low (L) frequency. The attenuation values are expressed by a number preceded by the letter of the frequency at which refers number.
SNR: indicated by a single attenuation level of protective value.
In the case of this model,
