A few too many gunshots, a few too many turboprop engines, and a few too many large pieces of plate metal being dropped lead to tinnitus. Ask me how I know.
Anyway, in a "why didn't we think of this before" moment, it seems there is a therapy undergoing trials in which most of the people get relief from their tinnitus, compared to a 'placebo' therapy. They play back for people, what the people say their tinnitus sounds like. For hours a day, for weeks, then off and on for a few months.
For £4,500. You can buy a decent synthesizer and an ipod for less than that, though, so enterprising DIY'ers with tinnitus might be in for a personal triumph if this proves as easy as it sounds.
Hat tip to Instapundit. Who for the last day appears not to have mentioned the French Jewish school shooting at all, either - like the rest of the US press.
