This may seem like an odd question, but is it socially acceptable to wear earplugs or noise cancelling headphones at one of the live music events on the ship? Many years ago I went to a live music event for the first time, and came away with tinnitus that never went away. Afterwards I've been very protective of (what remains) of my hearing, so I never blast music or like to put anything loud beyond what I can hear at normal volume. A premium noise cancelling headphone is also one of the very few things I splurge on, and I never travel anywhere without it.
So that being said, as a person who is extremely sensitive to noise and don't want my tinnitus to get worse, would I be okay wearing headphones to a live music event to dilute the sound? Would they think it's rude of me or not allow me in? I still want to hear new music, but just not at a very loud volume. I can probably just stand outside and listen but then I don't want to look really awkward doing that...
