Lin’s research builds upon earlier hypotheses positing that the crest of Parasaurolophus functioned as a resonating chamber, supporting vocalization similar to modern birds.
Lin’s experiments suggest that the sounds produced by Parasaurolophus may have resembled those of brass instruments, like a trumpet, though soft tissue implications suggest they could sound like a clarinet.
The initial hypothesis regarding the acoustic function of the Parasaurolophus’ crest dates back to Carl Wiman in 1931, demonstrating a long interest in dinosaur vocalization.
Lin's mathematical and empirical model updates previous theories about the resonance properties of Parasaurolophus, and he aims to adapt his findings to study other similar creatures.
