I have bi-annual hearing tests at my work and last year my hearing was down in my left ear, it wasn’t bad but enough to show up, I don't rehearse near our drummer but my trace is on a chair. That’s it the doc says, but 6 months on and my next test was done by another doc and both ears were the same. After thinking about it, it turns out that I had gone to see Tesseract in a small Glasgow club the day before that test. I do remember thinking it was probably the loudest gig ever and it had sort of temporarily dulled my hearing.
