T-Rex roars from ‘Jurassic Park’ were created with the sounds of this gentle animal

It was in 1993 that “Jurassic Park” hit the theaters, a movie that showed what would happen if different species of dinosaurs could be brought back to life to put on display, like a zoo.

Despite the technological obstacles of the time, director Steven Spielberg assembled an excellent team to recreate the dinosaurs, but a challenge arose: what did these animals sound like if their shape was known only from the remains of their bones?

This is how the dinosaur sounds from ‘Jurassic Park’ were created

In the cinematic world, the roar of the Tyrannosaurus rex (T-Rex) is as recognizable as its imposing figure, the sound of which was created by a clever combination of recordings of real animals.

Scientist and digital creator Joel Cabezas, @chilean_birds on Instagram, shared on his social network a clip of an interview with Gary Rydstrom, a sound designer, who revealed that one of the sounds of this dinosaur was created by a koala.

‘Jurassic Park’, groundbreaking sound quality

According to information from the CBR site, ‘Jurassic Park’ presented a unique experience to the audience as it was the first film with a Digital Theater System (DTS). Due to the high demands of the production, the sound of the dinosaurs was key, as they not only had to look terrifying, but also had to inspire fear just by hearing them.

Without exact scientific data on what a T-Rex would actually sound like, Rydstrom turned to creativity. He spent months recording real animal sounds, looking for unusual and exciting noises. The key was not only mixing the sounds, but also adjusting the frequencies to achieve an impressive effect.

So he combined the squeal of a baby elephant, the gurgle of an alligator and the growl of a tiger. The low-frequency elements came from the alligator, while the high-frequency elements came from the baby elephant. The result was a roar that no one had heard before and which is part of cinema history, since this sound was used for other films in the franchise.
