NASA's Mars rover Perseverance has found that sound travels much more slowly on the Red Planet than it does on Earth
and behaves in some unexpected ways that could have strange consequences for communication on the planet.

  At frequencies above 240 Hertz, "the collision-activated vibrational modes of carbon dioxide molecules do not have enough time to relax, or return to their original state,"
  the researchers said, which results in sound waves at higher frequencies traveling more than 32 feet per second (10 m/s) faster than the low-frequency ones. 
  That means that if you were standing on Mars, listening to distant music, you would hear higher-pitched sounds before you would hear the lower-pitched ones.

So...
Music from far away may sound funny?

For Mars we will need compensation headphones with distance measurement and variable delays....
;-)

Better use radio.. and earplugs/ headphones...
