Mar 24, 2022 · That's why sound travels about 343 meters (1,125 feet) per second in our atmosphere at 20 degrees Celsius, but also at 1,480 meters per second in water, and at 5,100 meters per second in steel. Mars' atmosphere is a lot more tenuous than Earth's, around 0.020 kg/m 3, compared to about 1.2 kg/m 3 for Earth.
Apr 6, 2022 · Mars' barely-there atmosphere is over 100 times thinner than that of Earth, so sound moves much more slowly through it, traveling at just 787 feet per second (240 m/s), according to Science Alert ...
Apr 11, 2022 · On Mars, the speed of sound depends on its pitch. All sound travels slower through Mars’ air compared with Earth’s. But the higher-pitched clacks of a laser zapping rocks travels slightly ...

Sound travels slower on Mars as compared to Earth because Martian Atmosphere is about 100 times less dense than Earth and is barely present due to carbon dioxide—resulting in very low atmospheric pressure on mars’ surface. Below are the 7 reasons why the sound travels slower on Mars than on Earth:
The speed of sound is determined by the properties of the medium through which it travels. In a gas, such as the atmosphere of a planet, the speed of sound is determined by the temperature and density of the gas. The speed of sound is directly proportional to the square root of the gas temperature and inversely proportional to the square root of th...
The speed of sound is directly related to the density of the medium through which it is traveling. On Earth, the density of the air is relatively constant at sea level, so the speed of sound is also relatively constant. However, on Mars the atmosphere is much thinner, which means that the density of the air is much lower. This lower density results...
Sound travels faster in warm air than in cold air. This is because the molecules in warm air are farther apart than the molecules in cold air, which means that the sound waves have more space to travel through. On Mars, the average surface temperature is around -80 degrees Fahrenheit (-62 degrees Celsius), which is much colder than the average temp...
The speed of sound is also affected by the composition of the gas that makes up the atmosphere. The speed of sound is different in different gases because the properties of the gas, such as its density and compressibility, affect how sound waves travel through it. The atmosphere on Mars is primarily composed of carbon dioxide, which makes up about ...
On Earth, the gravitational force is relatively constant at sea level, which means that the density of the air is also relatively constant. However, on Mars, the gravitational field is weaker than on Earth, which means that the density of the air is also lower. The weaker gravitational field on Mars means that the air molecules are less tightly pac...
The surface of Mars is also different, it’s covered with dust and rocks and the sound can be absorbed or scattered by these surfaces. This is due to different acoustic properties that can affect how sound waves travel through them. On Mars, the surface is primarily composed of rock and soil, which are relatively good conductors of sound. However, t...
Water ice is known to be a good conductor of sound, and it is believed that subsurface permafrost on Mars may also contain water ice. If sound waves were to travel through layers of water ice or permafrost, they would likely travel faster than if they were traveling through rock or soil. However, the presence of water ice and subsurface permafrost ...
The sound on Mars is astonishingly soft when we hear that sound. “When the sound was silent, we thought that the microphone was broken,” said Sylvestre Maurice, a talented astrophysicist at the University of Toulouse in France. NASA said “Except for the wind, Natural sources of sound are unusual on Mars.” NASA scientists predict that there will be ...
Why Mars has Two Speeds of Sound?
Researchers discovered about two speed of sound on Mars, first is for high-pitched sounds whereas the other is for low-pitched sounds. Mars has two sound speeds because of the higher availability of carbon-dioxide in its surface atmosphere.
What happens to sound on Mars?
Sound does not live upto long time because of the cool and thin air on Mars, thus it will not go to long distances.
Why do the sound pitches change in the Mars’ environment?
The change of sound pitches is due to the very low atmospheric pressure on the surface of Mars.
Jun 19, 2024 · A composite panorama of Mars taken by NASA's Curiosity rover at two different times of day — 8:30 a.m. and 4:10 p.m., local Mars time. New research finds that sound moves differently at ...

Jan 12, 2022 · On Mars, sound waves vibrate much differently than they do on Earth, and the sounds that travel along these sound waves are muffled. That’s because the atmosphere on Mars has a very different ...

Mar 29, 2022 · This is why sound travels much slower on Mars (240 m/s) than on Earth (343 m/s), a fact that scientists have long known. But instruments on board Perseverance were able to determine something scientists did not already know. That sounds that were under 240 hertz (Hz) traveled even slower than that—just 230 m/s.
