The speed of sound on Mars is weirdly different

Scientists have discovered that Mars has a strange speed of sound that could have other implications for the future communications of Martians on Earth. Using different types of devices, scientists found that when trying to talk on Mars, the planet's atmosphere creates a strange effect, as high-pitched sounds travel faster than low-pitched sounds. At the 53rd Baptiste Chide Lunar and Planetary Science Conference at Los Alamos National Laboratory, these results were revealed to all the scientists present, explaining that high temperature fluctuations on Mars could be the reason and should be investigated. The speed of sound can be affected by the density and temperature of the medium through which it travels. The denser the medium, the faster the sound travels. The Martian atmosphere is much thinner compared to Earth, about 0.020 kg/m3 on Mars and 1.2 kg/m3 on Earth. In addition, the Martian surface generates convective updrafts during the day that create intense turbulence. Scientists used unique microphones to listen to Martian sounds and a laser that generated timed noise, while the SuperCam microphone was used to record sound pressure variations from the Rover Decay Spectroscopy instrument that extracted rock and soil samples from Mars.

The team of scientists measures the time between the laser closure and the sound that reached the supercam microphone at a height of 2.1 meters. This was used to measure the sound speed on Marty's surface. One of the researchers wrote in their conference document that "the speed of sound recovered by this technique is calculated throughout the path of acoustic propagation that passes from the ground to the height of the microphone. Therefore, at each given wavelength It fell by the variations of the temperature. And the wind speed and the direction along this path ". The results of the research and research showed that the sound speed on the Mars on the environment is provided about 240 meters per second. One of the raserrger performs the results of the results of low pressure carbon dioxide molecules. With a frequency of 240 Hertz, the vibration mode of carbon dioxide molecules is not relaxed, resulting in a sound that drives faster at higher frequencies with more than 10 meters per second. This was called by scientists as a "unique listening experience" as a highly accurate sound faster than low noises.
