   Apr 30, 2024 · Sounds emitted in the cold Martian atmosphere would take slightly longer to get to your ear. With an average surface temperature around -81 F (-63 C), Mars has a lower speed of sound, around 540 mph (~240 meters per second), compared to about 760 mph (~340 meters per second) on Earth. You probably wouldn’t notice up close, but over longer ...

   Mar 24, 2022 · 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. That alone means that sound would propagate differently on the red planet. But the layer of the atmosphere just above the surface, known as the Planetary Boundary Layer, has added complications: During the day, the warming of the ...

   How fast does sound go on Mars?

   • With an average surface temperature around -81 F (-63 C), Mars has a lower speed of sound, around 540 mph (~240 meters per second), compared to about 760 mph (~340 meters per second) on Earth. You probably wouldn’t notice up close, but over longer distances you might. The sound level you'd hear would be automatically lower on Mars.

   Why does Mars have a high speed of sound?

   • "Due to the unique properties of the carbon dioxide molecules at low pressure, Mars is the only terrestrial-planet atmosphere in the Solar System experiencing a change in speed of sound right in the middle of the audible bandwidth (20 Hertz to 20,000 Hertz)," the researchers write.

   Can you hear a sound on Mars?

   • On Mars you’d have to be much closer to the source of a sound to hear it at the same volume as you would on Earth. The atmosphere of Mars, made up of 96 percent carbon dioxide, would absorb a lot of higher-pitched sounds, so only lower-pitched sounds would travel long distances.

   Could a Mars rover reveal the speed of sound?

   • Artificially colored image of Martian sunset. (NASA/JPL-Caltech/ASU/MSSS) Scientists have confirmed the speed of sound on Mars, using equipment on the Perseverance rover to study the red planet's atmosphere, which is very different to Earth's. What they discovered could have some strange consequences for communication between future Martians.

   Apr 1, 2022 · On Earth, sound might drop off after about 213 feet (65 meters); on Mars, it falters at just 26 feet (8 meters), with high-pitched sounds being lost completely at that distance. The recordings from SuperCam’s microphone also reveal previously unobserved pressure variations produced by turbulence in the Martian atmosphere as its energy changes at tiny scales.
