I use the 3M E-A-R plugs at home and love them. Since my tragus doesn't fold over, I am unable to use traditional Apple earbuds or other things that just fall out of my ear. 3M E-A-R plugs are like memory foam and fit snugly, providing excellent noise reduction. I use ComplyFoam on in-ear headphones for the same reason, because those thin rubber ear bud covers are useless. http://www.amazon.com/3M-E-A-R-Classic-earplugs-Pair/dp/B007GBUC7M matthew black california state university, long beach -----Original Message----- From: NANOG [mailto:nanog-bounces@nanog.org] On Behalf Of Nick Hilliard Sent: Wednesday, September 23, 2015 2:34 AM To: nanog@nanog.org Subject: Ear protection What are people using for ear protection for datacenters these days? I'm down to my last couple of corded 3M 1110: http://www.shop3m.com/3m-corded-earplugs-hearing-conservation-1110.html These work reasonably well in practice, with a rated nominal noise reduction rate of 29dB. Some people find them uncomfortable, but they work well for me. There are other ear plugs with rated NRR of up to 32-33dB. Anyone have any opinions on what brands work well for them? Nick
