Not where I am standing right now!

(I mean, maybe you’re right in some places, but it’s certainly not everywhere. Ironically, I happened to be standing next to a completely empty crossing, gates down, bonging away, while reading your comment.)

The nearest crossings where I live indeed stop the chimes when the barriers have been lowered. This doesn't actually make much of a difference really, because the train arrives only a few seconds after, and, because it's a local line, there are never more than three cars in the train so it passes very quickly.

Not that I'm bothered by the chimes at all. And grandson loves them.
