The results of a study aimed at calculating the speed of sound Mars Was recently presented at the 53rd Lunar and Planetary Science Conference at Los Alamos National Laboratory. They concluded that it would actually be difficult to talk there, Mainly because high frequencies would reach us earlier than low frequencies.

But it is the best way to get into the situation Knows what human voices sound like on the red planet. Therefore, the authors of this survey, based on data obtained by the Perseverance tester, They have created a website where we can conduct this exciting test.

In this section you can not only see what any human voice recording on Mars would look like. also On the piano you can hear birdsong, sea waves, Ingenuity helicopter flight or even Claude Debussy Moonlight.

As the study authors explained in the statement, it was difficult to obtain data for this experiment. And that’s the fact that, apart from the wind, Mars is a pretty quiet planet. So to show the results, they also use the sounds of the earth, But forget that very few voices are heard there. Of course, if one thing is clear from all this, it is that the red planet is completely free from noise pollution.

How does any human voice sound on Mars?

In a previous study by this science, they came to several conclusions. For starters, there are very obvious changes at different heights. It is known that the speed of sound depends on factors such as the environment in which it moves and the temperature. For example, The speed of sound on Earth is usually 343 m / s. However, this is the number for the combination of gases in our atmosphere, at 20 ° C. If the water was at a temperature of 25 ° C, it is 1593 m / s.

Mars has the disadvantage of that Its atmosphere experiences very sharp temperature changes at different altitudes. Therefore, the speed of sound varies considerably depending on the pitch at which it is measured.

In addition, it contains low-pressure carbon dioxide, which has an interesting sound effect. Frequencies above 240 Hz are most relevant; The sound moves at more than 10 meters per second. Hence, loud noises reach us faster than low noises.

Finally, the study authors highlight the problem of sound pressure, more collectively, volume. ᲡOn average, The sound of the same source is 20 decibels lower on Mars than on Earth. This is clearly seen in the posts posted on the NASA project Perseverance page.

A website that can simulate someone’s voice on Mars

Included This is a site where you can find out what the voice of any person on the red planet will be like. The only thing to do Select the tab for this purpose Home and once inside Press the microphone When recording up to 10 seconds.

Leave a page to delete a post, But it can be downloaded in WAV or MP3 format. Of course, it is important to know that when a person has downloaded the final result, The sound is heard first on Earth and then on Mars.
