Many years ago and a long time after I left the R.A.F my hearing was checked and I was given an award of, if I remember correctly, £1500. This was put down to flying several thousand hours in the left hand seat of a Shackleton listening to the mighty Griffons. Then a few years later ( don’t ask!), I was asked to go for a further test and was diagnosed at over 20% loss of hearing. I was given a war pension of £1500 annually, I had to pay back the initial award but have enjoyed many years of the present one. For those “Growlers” still with us, try again. Best wishes
