Well what this video fails to mention is the fact that a T Rex and any other dinosaur for that matter, is no more closely related to crocodile or bird than a sparrow is an American Alligator. Using any existent species of archosauria to determine what a T Rex would sound like would be no more accurate than than using a humming bird to figure out what a crocodile sounds like.

Granted Infrasound would likely be the go to method of long distance communication for any animal that size. However a bellowing roar may also be just as useful. What'd be truly terrifying is a combination of both. An animal with lung capacity of a Tyrannosaurus letting loose a bellow like that could potentially produce enough decibals of infrasound to produce a concussive blast capable of stunning prey at close range, similar to how a some species of whales and dolphins weaponerize their echolocation.
