Sounds even a bit like Godzilla, yes.

What I find interesting is, that most of those screenmonsters and dragons sound like this.
I mean this kind of disturbing roar, that is like something hitting a kind of subconscious fear.

Saw a research, where they explained why some sounds sound so disturbing to us, like chalk on a blackboard and the result was, that it sounded similar to some bird or something and this one was the descendent of a prehistoric Raptor kind of thing and a good old enemy to our ancestors.

So if sounds like this are somehow recorded in our collective subconscious or in our DNA, than it´s not too far fetched, that we know those trumpet sounds from days our ancestors witnessed happenings that are in connection to these sounds.
