I had a couple of head injuries when I was in my twenties, and soon after the second one I started to go deaf. For a while I did what any well-adjusted adult would do; I pretended it would all go away. When that was no longer possible, I went along to the local audiology department who told me that my hearing in both ears was already down about 50%. They issued me with a pair of analogue hearing aids, and that was pretty much it – I just went home and got on with life.
