I've got a slight tinnitus damage from working as a carpenter often forgetting and/or not bothering to use hearing protection for a couple months, as well as a few too many high volume competitive Call of Duty 4 matches to hear footsteps back in the days, so I'm lucky enough to hear that sound 24/7 as long as there's no other sounds to drown it out (its at it's loudest when I try to sleep). I'm also way more sensitive to loud noises and certain frequencies, some are even physically painful to my eardrums at normal talking volume (I've got a mild case, it can get a lot worse). Do not ignore his closing statement.
