First audio recorded on Mars reveals two speeds of sound

The first audio recordings on Mars reveal a quiet planet with occasional gusts of wind where two different speeds of sound would have a strange delayed effect on hearing, scientists said Friday. The study confirmed for the first time that the speed of sound is slower on Mars, travelling at 240 metres per second, compared to Earth's 340 metres per second.
