Brown’s projects focus on the sound-making abilities of the Corythosaurus, investigating the changes in vocalizations throughout different life stages. The earlier project, Rawr!, utilized a mechanical larynx, but hygiene concerns during the pandemic prompted a transition to a computational approach in Dinosaur Choir. This project began in 2021, with updated research in Canada, analyzing CT scans and fabricating a life-sized skull replica. Enhanced modeling tools allowed for detailed exploration of dinosaur vocal mechanics without starting from scratch, showcasing an innovative blend of paleontology and technology.
With Rawr!, we used a mechanical larynx, so people would have to actually blow into a mouthpiece to create the sound. But once we started exhibiting it, we realized it wouldn't be possible for people to interact with it in a way that was hygienic-and the pandemic solidified that. That's when I started thinking about something more computational.
I'm extremely proud of my nasal passages. I learned CT segmentation for about a year to get them as accurate as possible, taking into consideration the effects that being buried for millions of years would also have had on them.
The models are based on a set of mathematical equations that relate to the mechanics of the voice-things like changes in air pressure and the length of the vocal tract.
The work into Dinosaur Choir officially began in 2021, with Brown travelling to Canada, where the Corythosaurus is supposed to have lived, to update her research.
