NASA has determined the speed of sound on Mars and explained its unevenness
Due to the subtle atmosphere on Mars, the sound does not spread as well as on our planet. NASA has analyzed recordings from the microphones of the Perseverance rover and the Ingenuity drone to determine how fast the sound wave is moving. The results of the study published in the journal Nature on April 1.
The carbon dioxide atmosphere on Mars has found to slow down the sound, but the high frequencies are slightly faster than the low frequencies at 900 km/h versus 864 km/h. For comparison, the sound on our planet has a speed of ≈ 1191 km/h.
On Earth, the sounds of an orchestra reach you at the same speed, whether low or high. But imagine, on Mars, if you are far from the stage, there will be a long delay
Sounds on Mars are even less tenacious. Due to the subtle atmosphere at a distance of 4 meters, you heard the interlocutor as if he were 65 meters away from you on Earth. NASA showed how birdsong, the ringing of a bicycle, the signal of a passing truck, ocean waves and music on Mars could sound.
