NASA published a new paper in the scientific journal “Nature” on the 1st of this month, which mentioned that the research team used the Perseverance rover to record various sounds on Mars, including Perseverance and the breeze and other sounds. The study of the sound sent back to Earth by the Perseverance rover to simulate the sound on Mars. In order to satisfy astronomy enthusiasts, NASA uploaded a Mars simulation sound on YouTube for the public to experience the difference between Mars and Earth.

The paper mentions that the sound source will use the atmosphere as the medium of transmission, which will affect the sound transmission. On Earth, sound generally travels at a speed of 343 meters per second, while Mars has about 95% higher carbon dioxide content. The speed of sound transmission varies by pitch or frequency. Bass generally travels at a speed of 240 meters per second, and treble At 250 meters per second, the overall speed of sound travels slower than on Earth.

Sylvestre Maurice, lead author of the paper and an astrophysicist at the University of Toulouse in France, said the most striking feature of the recordings was that Mars was often silent for long periods of time. At some point, he even thought the microphone was broken, because it was too It is quite now. Baptiste Chide of Los Alamos National Laboratory in New Mexico also said that Mars is very quiet because the atmosphere is so thin.

Taking listening to a symphony orchestra as an example, Maurice explained to the public that on Earth, both high and low frequencies will be heard at the same time; but on Mars, if you are farther away from the stage, you will hear a significant delay in the high and low frequencies, even if the high and low frequencies are emitted at the same time. , you will still hear the treble before the bass.
