It is named "times of tumult" for a reason.

yeah they were probably very quiet for their size
but also based on the distance between their eyes, socket orientation, and eyeball size, they likely had better visual acuity than modern birds of prey, so possibly the best visual acuity of any animal ever.
they had unusually long cochlea in the ear, which indicates high auditory acuity specifically in low ranges, meaning that they could hear the footsteps of prey over long distances
they had unusually large olfactory bulbs, indicating a powerful sense of smell
and they had the largest brain:body ratio of any dinosaur outside of some small microraptors
so not only were they one of the largest land predators of all time, but they had some of the best vision, hearing, smell, and intelligence of any comparable predator. A t rex would be able to see, hear, and probably smell you at a distance where a human would not be able to see the t rex without binoculars.
