Elon Musk, the founder of SpaceX, has chosen Mars as a new home once Earth runs out of supplies. However, it must be taken into consideration that the atmosphere of Mars mainly consists of carbon dioxide, which reduces noise levels by a significant margin. If you and another person were to talk right next to each other using a normal voice, it would seem as though you cannot hear each other clearly.
Baptiste Chide is a planetary scientist and member of the Los Alamos National Laboratory. He and his colleagues shared this information in the May 26 issue of Nature. They were able to analyze the first sounds ever recorded on Mars, which was the sound of the Perseverance rover firing lasers at rocks. This caused vibrations similar to thunder, but on a much smaller scale. “It’s a pretty drastic difference from Earth,” Chide said.
Mars has a strange way of sound travel. High-pitched sounds travel at 559mph while low-pitched sounds travel at 539mph, which drastically differs from Earth’s singular 761mph. Sound waves add molecules into the air while travelling, which is known as the “relaxation” effect.
However, it changes based on the sound frequency and molecule types. On Mars, high-pitched sounds move quicker than low-pitched ones. This allows scientists to study how living on Mars would feel like as air humidity, humidity, and temperature are all affected by the sound travel speed.
