If your travelling...?

Question

at the speed of sound and you f**t can you hear it??

Answer 1

...and, of course, the first thing that springs to my mind is: Why did you choose 'f**t'?  Why not 'speak' or 'turn on the stereo' or 'sing a happy song'?

Anyway...yes, you can hear it.  The sound waves eminating from your body (whether they come from your a**s or your mouth) would already be traveling at a relative speed, faster than the speed of sound.  You could hear them just fine.  After all, how do you think jet pilots would use a radio if they couldn't make a audible sounds?
