There is actually 2 different speeds for sound on mars.

Its speed depends on whether the sound is high-pitched or low-pitched
The speed of this sound is about 250 meters per second, the team reports. That’s slower than on Earth, where sound travels through the air at about 340 m/s.
Martian surface at frequencies below 240 hertz, or slightly deeper than middle C on a piano: 240 m/s.
