Recent in-situ acoustic recordings and modeling confirm that sound propagation on Mars differs significantly from Earth due to its carbon dioxide atmosphere and low pressure.

The analysis

The retrieved papers include direct in-situ measurements and modeling of Martian acoustics using data from the Perseverance rover, confirming distinct sound speeds, attenuation, and vibrational relaxation effects linked to the carbon dioxide-dominated atmosphere.
