I 110% sympathise Tilly - After years of playing the decks to astronomical volumes and going out to loud clubs in his yoof, My OH can't have the TV at a normal volume - It quite literally hurts my ears.
I came up with a solution, whilst I had some time off, I decorated the Attic room, turfed out all the junk and turned it into a 'Man-Cave' for him - now he can have his decks and TV at whatever volume he wants with the door shut and I can peacefully type away on my laptop downstairs with the hound. He loves the man-cave too xx
