BTW, at the bottom of this page is a chart in blue showing how long you can be exposed to various levels of sound before hearing loss begins. Concerts generally are pretty close to 100dbs. So if you are starting to get hearing loss after 15 minutes, how much hearing loss will you get after all day at PPUSA? If you use the Etymotics, they cut out 15dbs. That gives you 8 hours before hearing loss starts.
