[Shop-talk] Hearing protection for mowing

[Jim Stone]

"While I'd love to have a pair of Bose Quiet Comfort 20…”

Just for what its worth, I am on my third set of the Bose QC20’s and could not live without them.  They work incredibly well, but I don’t know if they qualify as hearing protection.  As I understand it, they work by generating anti-noise: the opposite wave length of the noise coming in.  While what you can hear is greatly diminished - they are awesome on airplanes and in hotels with noisy HVAC systems - I wonder if they actually prevent hearing damage.   It would be nice to know if they do qualify, or if noise+anti-noise is still damaging to the ears, even if you can’t actually perceive it.  Does anyone here know?
