Question

Why we can't hear sound in mars?state the reason?​

Answer 1

Answer:

The sound level you'd hear would be automatically lower on Mars. The Martian atmosphere is about 100 times less dense than on Earth -- that is, there's just a lot less of it. That affects how sound waves travel from the source to the detector, resulting in a softer signal

Answer 2

Explanation:

Because Mars has a distinctly different atmosphere to Earth, NASA said a myriad of factors affect the way sound is transmitted on the planet. The cold Martian atmosphere, for example, would cause sound to take slightly longer to get to your ear.
