If you're regularly doing ensemble stuff, you can get hearing damage from the consistent loud volume. Thus, earplugs. It's maybe less significant for choir compared to e.g. rock band with amps or wind band with tons of brass, but you can still get ear damage. (That's where I got my tinnitus from lol) They do make specialized earplugs for music that allow some amount of pass-through, and don't isolate as much.
