Why not use headphones, so you can enjoy noise without bothering people who don’t like noise? Some noise can be uncomfortable to people at an airport. Movies with gunfire or shouting for example.
It's absurd that people would all have to carry around and use headphones just because some people don't want noise in public. I would agree that loud gunfire isn't appropriate in an airport but that's not the case here and you're misconstruing the situation to make your case sound better.
