The humming sound was partly based on that motor.” It was an old motor on a projector at the USC Cinema Department. When I read the script, I immediately had something in mind. Burtt said the noise was there from the beginning: “Oddly enough, it was the first sound I ever made for Star Wars. The elegant weapon comes with a range of noises - powering up and down and strikes in combat - but they’re all familiar. When attending any sort of Star Wars event, the sound I hear fans replicate the most is the distinctive thrum of a lightsaber. Burtt created the sound by placing a microphone inside a regulator on a scuba breathing apparatus and breathing into it in different ways. It emphasizes the fact that he’s more machine than man and makes him more ominous. The sound of the Sith Lord’s breathing adds to the intimidation factor. You can sometimes hear Darth Vader before you can see him. But it was something that we arrived at very slowly.” The combination camouflaged the two sources, and we found that we could get Artoo to act. He said, “We ended up with a 50/50 mix of electronic synthesizer-generated sound and my voice making funny inflections. He used a synthesizer, but he couldn’t capture emotion with it.

R2-D2 wouldn’t be the same without his whistles and beeps. These are five of the iconic sounds from the saga: His efforts added to the worldbuilding and made the Star Wars universe a more realistic, complete place. Sound designer Ben Burtt did remarkable work by gathering sounds in the field and manipulating them in imaginative ways.
