Can anyone explain the sound in the clip? So Mars atmosphere is different, making sound travel different? But the weird echo and metallic muffle, what explains

Can anyone explain the sound in the clip? So Mars atmosphere is different, making sound travel different? But the weird echo and metallic muffle, what explains that - why would the machine be particular noisy?

A Dutch article about this [1] said: > According to the Chinese space agency CNSA, the sounds are caused by the interaction of different metal parts. In the video, they also quote the person leading the Mars programme: > The sound is made by wheels rotating on the surface of the Mars rover. Basically, the sound of different metal objects bumping into each other.

  Hmmm, I've heard plenty of metal things bumping into each other, this sounds more like 0.1 bits/s sloshy MPEG audio. What I'd like to know is, is this actually how it sounded there, or are we mostly hearing compression artifacts?

    Why would it be compression artifacts when they are also sending hires video signal? This page has some simulations: https://mars.nasa.gov/mars2020/participate/sounds/ https://mars.nasa.gov/mars2020/participate/sounds/

    Yeah, I thought it sounded like flanging.

    It should indeed sound distant and muffled with the composition and temperature of Mar's atmosphere. Saw a neat pseudo-documentary on this not too long ago: https://youtu.be/OeYnV9zp7Dk?t=551 https://youtu.be/OeYnV9zp7Dk?t=551

      Kind of ridiculous to demonstrate what things sound like while playing eerie random background music over it.

  Would you say Dutch news is more objective than American news?

    No, it's just the news I happen to follow because I am Dutch, and it contained the info they were asking after.
