Ambient noise data collected by the InSight lander's seismometer gives us a detailed look at what lies right underneath its surface.
The speed of sound on Mars, within the audible bandwidth between 20 Hz – 20 kHz, varies depending on pitch, seemingly due to the low pressure and thermal turbulence of Martian surface air; and, as a result of these conditions, sound is much quieter, and live music would be more variable, than on Earth.
