@StrongBad, Thanks for that detailed answer,
outdoors.stackexchange.com/a/20768/5547 to @CharlieBrumbaugh's question about safe decibel levels,
outdoors.stackexchange.com/questions/20756. As someone who knows more than I'd like to about those problems, the more information, the better. @Cha, your hearing is important to me, as it is to the community in general! I have no idea who downvoted or why, so I'm not saying you did. I'm just thanking StrongBad for the answer!
