Answer 1

We have their avian descendants to look at, as well as other large animals. That gives us a reasonable idea of the pitch/volume a dinosaur might have.

But it is important to remember that there is no guarantee. [The things you see in a fossil are not even close to the whole picture.](https://xkcd.com/1747/)
