Deaf/HH travel

So I’m deaf and I’d like to get some tips for traveling as a deaf person. How do you navigate airports, bus stations or train stations, and how do they notify you when it’s time to board? Also I know I’ll need to watch the flight attendants for demonstrations, as well as lights on the plane for turbulence or to buckle your seatbelt, etc. What if I’m in a hotel and there’s an alarm like a fire alarm? Do I need to ask for them to call me or do they come notify you? I’d like to know if there’s any accessibility for deaf travelers. Thank you in advance
