The trick that worked for me was to use something like https://coffitivity.com/ https://coffitivity.com/. The sound is similar enough to the usual office noises and thus is very effective in cancelling them out. Also it has enough chaos to avoid becoming a distraction by itself. And then it doesn't hurt your hearing that much because you don't have to turn the volume too high to be effective. I like to combine it with a little music. The only problem is, I can't find headphones that don't hurt after an hour...
