There are so many unique sounds in the Star Wars films, from blaster pistols to lightsabers and speeders. The sound effects that are found inside the Star Wars movies are iconic and how these sounds are obtained may surprise you.

One very interesting sound in Star Wars: Episode II was the sound of the speeder diving. This sound was obtained by using a 1942 gas air raid alert siren in a parking garage, which created an echoing sound. Without knowing anything about how they obtained this sound and watching the movie, you wouldn't notice that it was a siren making the sound of the speeder diving, but after knowing what the sound is I can really hear the siren. It's amazing the sounds that we miss and don't think twice about while enjoying the experience. I wonder how many other familiar sounds we hear every time we watch movies and never notice.

For the sound of the gunships a biplane was recorded taking off and accelerating. I think that this choice of sound effect really compliments the sound of the gunship because they are both air vehicles and the sound feels natural to me when I hear the sound of the biplane matched with the gunship on screen.
Another really interesting sound design choice was in the Geonosian factory scene. Sounds of an actual factory was mixed with the sounds of drum percussion. This created a very convincing factory environment and the drums really complimented the sounds of heavy machinery smashing down the assembly line.
