Protective earmuffs protect an employee's hearing in work environments where noise levels are above 85 decibels. They consist of two lined cups that completely cover the ears to deaden sound. The cups attach to a headband for over-the-head wear or clip onto the sides of a hard hat. Protective earmuffs provide longer hearing protection at higher decibels than foam ear plugs. R.s. Hughes offers many headsets, earmuff hygienic pads, protective earmuff replacement parts, earmuff kits, ear plugs, and Fit test plugs for your needs.
