Scientists Use 3D-Printed Model to Recreate Parasaurolophus Sounds

A new study explores the acoustic properties of the dinosaur's crest to approximate its vocalizations.

Researcher Hongjun Lin from NYU has developed a physical model to study the sounds of Parasaurolophus, a duck-billed dinosaur from 70-80 million years ago.
The dinosaur's distinctive crest likely functioned as a resonance chamber, amplifying low-frequency sounds similar to modern brass instruments.
The 3D-printed apparatus, called the 'Linophone,' experimentally verifies a mathematical model of the crest's acoustics.
Initial findings suggest the dinosaur's calls were deep and resonant, with frequencies aligning with prior paleontological studies.
Future plans include refining the model using fossil scans and creating digital tools to simulate the sounds for research and creative applications.
