TIE in TIE Fighter stands for Twin Ion Engine

The reason we hear engine noises, blaster fire, etc in space battles is because these sounds are part of every starship's sensor package. It's played through speakers on the bridge, or in the pilot's helmet, to provide additional information and keep the pilot from constantly looking at a screen.

Edit: Apparently this came from the novelization of Star Wars, back before it was Episode IV A New Hope.
