How to cope with noise and other sleep disturbances

Hey ISFP. I have had many sleep issues regularly, mostly due to noise at night. I've tried ear buds and other solutions but nothing works.

I live with my father, brother and sister and sleep in the same room as my brother on a bunk bed. He's extremely noisy in his sleep, I don't even know how it's possible to make that much noise while sleeping but anyway lmao. Also no respect for basic social rules like coming home after midnight and slamming doors, starting homework at 11PM and in general doing completely inacceptable stuff socially.

What are your ways to cope with noise ? I'm very sensitive to it, probably due to my function stack I guess. I feel trapped in the sensory experience.
