Which type of dinosaur make a tuba sound?

The dinosaur commonly associated with making a sound similar to a tuba is the Parasaurolophus. This hadrosaurid, or "duck-billed" dinosaur, had a distinctive long crest on its head that is believed to have been used to produce resonant sounds, possibly for communication or mating calls. Scientists speculate that the shape of the crest could have allowed it to create deep, Trumpet-like sounds akin to those of a tuba.
