NASA specialists have created a website where users can listen to their voices on Mars
NASA has introduced a platform to test what it sounds like on Mars. This is “Sounds of Mars”, a website where people can test their voices on the fourth planet in the solar system.
On the same page of the experiment is evidence of other sounds such as the chirping of birds, the crash of a helicopter, ocean waves and even the famous “Moonlight” by the French composer Claude Debussy.
Specialists have created a website where users can hear their voice on Mars. The platform allows you to record sounds for up to 10 seconds and then download them in WAV or MP4 format in addition to listening online.
Mars, a quiet planet
This suggestion could be made by studying the speed of sound at different points in the galaxy. The analysis of Mars was presented at the 53rd Lunar and Planetary Scientific Conference at Los Alamos Laboratory, led by Baptiste Chide.
This data was collected by the rover Perseverance, a space reconnaissance vehicle. However, the authors of the study acknowledged that this was a difficult task because it was a very quiet planet.
The variables that change the way sound propagates from one point to another are related to the length, temperature, and pressure of the medium it transmits. Scientists have given the example that the speed of sound on Earth is 343 meters per second, but this is the number for the combination of gases in our atmosphere at 20 ° C. If we direct the water to 25ºC, it is 1,593 m / s.
But something else happens to Mars: its own atmosphere experiences sudden temperature changes at various altitudes. Therefore, the speed of sound can vary greatly depending on how high it is measured.
Slow sound at low volume
On the red planet, low-frequency sounds propagate at 240 m / s, while higher-frequency sounds propagate at 250 m / s; in both cases more slowly and in smaller numbers than on Earth. However, there are many differences on Mars, on the one hand, it contains carbon dioxide at low pressure, which has very different sound effects than the typical sounds of the world. Acoustic pressure also plays a role, the same sounds on Mars 20 decibels lower than on Earth.
The planet is generally quiet and some sounds are almost imperceptible due to its thin layer of atmosphere, which is 100 times less dense than on Earth.
For the same reason, the density of the atmosphere also changes, as carbon dioxide freezes in the polar caps during the winter and changes the noise by 20%.
The conclusions show that sound propagates more slowly on Mars itself, but especially high frequencies come faster than low frequencies, so the conversation may not be like us on Earth. This is because sounds with a frequency above 240 hertz propagate 10 m / s faster.
