I do white noise on headphones, help me focus for many many hours, YouTube is full of that, get some good mix of vacuum machines, hair dryer noise on multiple tabs, play around with what works best for you - try to look for a moment where it makes you feel goosebumps aka when you hit some kind of "resonance" then keep that playing and try to focus - don't fight the "noise" instead try to embrace it let it flow thru you and time will kinda cease to exist and work will get miraculously done :D
