I often have posted about how I wear ear plugs, and one fellow katrider asked me for the link to the article I referenced that said noise was damaging at about 30MPH. Well, here it is. Lots of other good info, too, and altho I usually don't care for commercial links, this one had some that got me thinking about alternatives to the squish-in ear plugs I currently use.
