How would your voice sound on another planet?

For the first time in history, scientists at the University of Southampton (United Kingdom) have used physics and mathematics to recreate the natural sounds of other worlds, from lightning on Venus to winds on Mars or the crunch of ice on the volcanoes on Titan, the moon of Saturn . In addition, they have modeled the effects of different atmospheres, pressures and temperatures on the human voice, and have incorporated it into software that allows transforming the sound of a voice on Earth to find out how it would be heard "out of this world".

The study's lead author, Tim Leighton, explained that on Venus the pitch of a voice deepens compared to levels on Earth "due to the planet's dense atmosphere ." "It means that the vocal cords vibrate more slowly through that soda soup that it has for atmosphere," he pointed out. However, the speed of sound is much faster than on Earth, so ultimately a man's voice sounds "like a deep-voiced Smurf," Leighton said.

Sounds can be heard for a world premiere at the Flight Across the Universe exhibition, which this month will host the Astrium Planetarium in Winchester, UK. Leighton noted that "at present, planetariums show images of bodies in the solar system, but there is no information about sound in the universe ." In his opinion, thanks to the research now presented "the human being will be as close as possible to spatial sound".
