Plugs in your ears and or thick isolations on your bedroom walls should help.
I might try earplugs again. I bought a pack when I moved in but I never found them super comfortable, I'd usually fall asleep and end up waking up and pulling them out after a few hours.

Having a pitch black room, covering any LEDs with electrical tape, and using an eye mask also help.
