V3 EAR-DEFENDER

Sound attenuation
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,
H 33
M 30
L 24
SNR 32

Viking series multiple-position earmuffs give workers the flexibility to wear their earmuffs over the head behind the head or under-the-chin. Viking earmuffs can be worn with other PPE, including hard hats, visors, face shields, respirators and welding shields. Plus, Viking's robust non-deforming dielectric construction withstands use and abuse while protecting your workers in electrical environments. The Viking series features patented Air Flow Control technology for optimal attenuation across all frequencies and also snap-in ear cushions for easy maintenance.

FEATURES

PATENTED AIR FLOW CONTROL™ TECHNOLOGY

Howard Leight's patented Air Flow Control delivers optimal attenuation across all frequencies, without increasing earcup size or weight. A patented baseplate chamber and high-tech non-woven layer manage the flow of air inside the earmuff to control how sound reaches the ear. The result is better, more consistent overall attenuation for virtually all industrial noise environments. Air Flow Control is a standard feature on all Viking series earmuffs.

• Multiple-position headband allows for a variety of wearing styles; a great alternative to cap-mounted earmuffs –
• wear when using other PPE
• Patented Air Flow Control™ technology delivers optimal attenuation across all frequencies, without increasing earcup size or weight
• Inner-ventilated headband reduces pressure on head; breathes easier in warm/humid climates
• Snap-in ear cushions make replacement quick and easy
• Elastic headband strap for better positioning when worn behind-the-head or under-the-chin
• Non-deforming, dielectric construction suitable for electrical environments
