Acoustic 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.
