I have serious tinnitus in one ear that causes me all sorts of issues, I wouldn’t wish this on anybody. Maybe I should thank my lucky stars.Then thank your lucky stars that humming isn’t an autistic trigger for you - some noises can literally cause us physical pain.
I did work in a customer’s property and they had a commercial country music station playing all day, to be honest it nearly made me want to go to the pub after work and start drinking again.
It was a light hearted joke but never mind
