Something has to vibrate, and the sound waves have to travel to your ears.
You need matter to vibrate at a frequency that is detectable to the listener.
sound is simply the vibration of air molecules. so, sound occurs whenever air molecules are vibrated. but in order for us as humans to hear that sound, the air molecules have to vibrate within a certain frequency range
medium
It must fly faster than the speed of sound
motion
Something must vibrate, to make the air (or whatever else the sound travels through) vibrate.

An atmosphere. Sound cannot travel in a vacuum.
because space is a vacuum. In order for sound to carry, there must be matter through which it may travel (sound is caused by the energy that causes particles to vibrate). On Earth, we have the air particles that sound carry's through. In space, there is no medium through which the sound energy may travel.
medium
The sound signal must firstly be changed into an electrical signal.
