And yes, sounds on Mars behave very differently.
The Perseverance rover not only allows us more on the surface of Mars . Their instruments also help us better understand how sound changes on the Red Planet .
NASA has activated “Sounds of Mars” an interactive tool that allows you to record an audio of less than 10 seconds and know how it would be heard on Mars .
Why do things sound different on Mars?
“Mars has an unusual atmosphere compared to Earth , with very different temperature, density, and chemistry. These differences have three main effects on what you would hear,” explains NASA .
The speed of sound: Sounds emitted in the atmosphere of Mars may take a little longer to reach your ears since the speed of sound is slightly lower on Mars: 240 meters per second, less than 340 meters per second on Earth. Land.
Volume : The atmosphere of Mars is 100 times less dense than that of Earth, so everything we hear would be heard quieter on Mars. You would have to be very close to the source of the sound to hear it at the same volume as on Earth.
Sound quality : The atmosphere, made up of 96% carbon monoxide, is capable of absorbing the highest sounds, so only low sounds can travel long distances on Mars.
The Tools of Perserverance on Mars
The Perseverance rover has two microphones on board, the first to operate on the surface of Mars.
