Heavy Duty Ear Muff with a light weight, adjustable frame by KNIGHT GAURD ER4

Product Description:

These safety ear muffs by KNIGHT GUARD are design to fully enclose the ears and protect them from high decibel sounds. Safety is the number one most important aspect of any project or job and the proper safety equipment is vital to keeping one safe, along with healthy and wise method and practice. Never compromise on safety, having these ear muffs with prevent you from that compromise. These muffs are adjustable, accommodating for various head sizes and are set on a metal frame that is durable yet lightweight. These feature super comfortable soft head contact foam that allows for extended use and application without causing fatigue or discomfort. This style of muff has the frame extend around the back of the cranium instead of over the head like most traditional ear muffs-this allows for the user to don a hard hat or other style cap if need be. Here are some tips to help you understand the level of noises and what ear muffs can help protect against:

    A typical conversation occurs at 60 dB – not loud enough to cause damage.
    A tractor that is idling (note that this is idling, not actively in drive) is loud enough at 87 dB that it can cause permanent damage after only 2 work days (10 hours).
    While listening to a music system with stock earphones at a maximum volume, the sound can reach a level of over 105 dB, loud enough to begin causing permanent damage after just 15 minutes day over day.
    A strike of thunder (120 dB) or a gunblast (135-192 dB, depending on weapon), can both cause immediate and severe damage.
    These ear muffs from KNIGHT GUARD can be used to reduce the exposure to high levels of decibels caused by the aforementioned common sounds.
