Filtered earplugs
Filtered earplugs are beneficial when individuals want to have the ability to hear their outside sounds, but still maintain a safe level of protection. They can be used in several industrial as well as recreational activities to “take-the-edge-off” harmful noise levels. (It is always E.A.R.‘s recommendation to have an audiogram taken after every year to make sure your hearing protection choice is doing its job correctly).
Acoustical Filtered Earplugs
These specialized patented filters are inserted into a custom mold to allow safe sounds, those below 80dB like normal conversation, to pass virtually unattenuated. Yet for sounds higher then 80dB, these filters act like mini-restrictors and limit the sound attenuation to OSHA regulated requirements. Best used for industrial noise and shotgun sports where individuals want to hear some conversation or audiotory signals coming from machinery.

Sonic Valve Earplugs
Sonic Valve hearing protectors are special patented hearing protection devices designed to allow low level sounds, not harmful to hearing, to pass through. But offer effective hearing protection against high level, high impulse noise which are harmful to hearing. Generally used in aviation, music and sound engineers to reduce "noise hangovers" and ringing ears.
