Check out how your voice will sound on Mars

They recently appeared on 53rd Los Alamos National Laboratory Lunar and Planetary Science Conference results of a study aimed at calculating the speed of sound on Mars. It was concluded that it would be difficult to actually carry on a conversation there, mainly because high frequencies reach us before low ones. But the best way to take a stand is to know how our voice would sound on the red planet. Therefore, the authors of this study, conducted with data obtained Persistent all-terrain vehiclecreated a web page where we can carry out this curious experiment.

In it, we can not only see what a recording of our voice would sound like on Mars. You can also listen the trill of birds, the waves of the ocean, the flight of an Ingenuity helicopter, and even Moonlight at the piano by Claude Debussy.

As the study authors explained in a statement, obtaining data for this experiment was difficult. And that’s what’s outside windMars is a fairly quiet planet. Therefore, they also used sounds from Earth to demonstrate the results, but not forgetting how little can be heard there. Of course, if there’s anything clear in all of this, it’s that the red planet is completely free of noise pollution.

How does your voice sound on Mars?

In a previous study by these scientists, they came to several conclusions. To start there very sharp changes at different heights. It is known that the speed of sound depends on factors such as the medium in which it propagates and the temperature. For example, it is often said that the speed of sound on Earth is 343 m/s. However, this number is for the combination of gases in our atmosphere at 20ºC. If we focus on water at 25ºC, that’s 1593 m/s.

Mars has a flaw in its own atmosphere. very sharp temperature changes at different altitudes. Therefore, the speed of sound will vary greatly depending on the height at which it is measured.

In addition, it contains carbon dioxide at low pressure, which has curious acoustic effects. Most importantly, above 240 hertz, sounds travel 10 meters per second faster. Therefore, high sounds reach us faster than low ones.

Finally, the authors of the study point to the problem of sound pressure, or, more simply, loudness. Average sounds from the same source Mars is 20 decibels lower than Earth. This is something that is clearly visible in the recordings published on the NASA Perseverance website.

And it is on the same site that we can see the Martian sound of our voice. You just have to select the tab indicated for it on the main page and once inside, keep the microphone pressed while we record for a maximum of 10 seconds. When you leave the page, the entry is deleted, but we can download it in WAV or MP3 format.

This is an example in which the voice is heard first on Earth, and then, as it were, on Mars. But dare you to see what yours sounds like? You know what you need to do.
