Well, I think you're clearly right on that point -- sonic booms, by definition, are not visible, they're audable.
But
this effect apparently occurs only at, or
very close to, the speed of sound, so it's the "visual counterpart" of a sonic boom. I suppose the phrase "Visible sonic boom" just appealed to me.
