The tag sound was merged into noise. I proposed the synonym 1.5 years ago: Should 'sound' tag be a synonym of 'noise'? The top-voted answer and comments there made a good case for them being separate, for example, [noise] doesn't make sense here: What are the triggers of the MD-80's takeoff configuration warnings? But I could not take my vote back, and it went through a few hours ago.
(For that particular MD-80 post it's now showing as [sound] due to a known bug / mod edit.)
@Sanchises recommended in a comment to use aural-warning, but that leaves visual warnings out.
Or something else? What are your thoughts?
