The Voice of Dinosaurs

So, I realized there doesn´t seem to be a thread about this very interesting subject- what do you imagine dinosaurs sounded like?

I suposse you all know about the Parasaurolophus call that was replicated (by reconstructing the creature's nassal passages inside the crest) by Tom Williamson of the New Mexico Museum of Natural History; if not, here it is:



So, I wrote to Williamson and asked if he had re-created the sounds of other dinosaurs, or if anyone else had done it after him. He said that, to his knowledge, no one has ever re-created the call of another dinosaur, but also mentioned that a certain Dave Evans of the Royal Ontario Museum had been reconstructing the narial passages of other lambeosaurs.

So I was a boy scout and contacted Evans to ask him the same. This is what he said:

Thanks for your email. It is really tough to reconstruct the sounds of the corythosaurs, because their nasal passages are quite convoluted, and there is a lot that we don't know. The passages are shorter than Parasaurolophus, so they would have made higher pitched calls, but other than that, we just don't know. I have been doing alot of CT scanning of corythosaurs with Larry Witmer, and we have generated some unbelieveably detailed and accurate reconstructions of the nasal cavity in these guys (the paper is coming out in september in a journal called the anatomical record). The next step would be to takes these 3D models and simulate blowing air through them, like Tom did with Parasaurolophus. We haven't quite gotten that far yet, but it is something that we have definitely thought about and that is on our list to do. So you might be hearing more lambeosaur calls in the future.

So, it seems that Parasaurolophus remains the only dinosaur of which we have an approximate idea of what it may have sounded like. But the point of this thread is to ask what YOU imagine other dinosaurs sounded like.
Did T-Rex had a bird-like scream maybe, instead of a roar as in every TV show and movie? Perhaps raptors were the ones calling each other with lion-like vocalizations? And what about sauropods? Did they communicate through infrasounds like many giant animals today, or where they perhaps making peacock or swan-like noises instead of the classic whale songs everyone relates to them by now?
