Alarm clocks in both ears full time, occasionally English sparrows chirping. A lot of my hearing damage was due to sitting on tractors for days on the farm.
We used to shoot 303 target rifles on the local Army ranges, no hearing protection, like smoking, we did not realise it hurt you.
One of our club members went to his doctor for help as the ringing in his ears sometimes made him dizzy
The doc's advice, quit shooting! This was in about 1964, in England.
