[title] Prolonged Wear Comfort Aids
[* black] For users who need to wear PAPR for over four hours, a few comfort measures are helpful
[* black] Neoprene foam 2-3 mm thick under fan mount can cushion the top of your head. Passing bolts through the neoprene will hold it in place.
[* black] Fan noise over prolonged wear can be hard on ones ears. Concert attenuators with limited sound reduction of 19 dB allow me to hear conversations and monitors, but protect my ears. Regular ear plugs have too much attenuation of 32-33 dB
