One more thought - Try searching IEEE Xplore. There are many articles listed when I searched for "Hipot", including one specifically related to assessing aging in systems using hipot. See this link for one article that looks promising: http://bit.ly/ndyh22. -- Doug Nix, A.Sc.T. IEEE Engineering &

First do no harm - review John's notes about the user and the various sensitivities of headphones etc and do some good engineering evaluation of why the output levels are set where they are, the cost to redesign, and the effect on your production schedule will help you decide to "fight or flight" a
