There’s been so, so much amazing design for this film series over the decades. Especially with regard to the sound design (known as foley). Iirc the ‘pew pew’ laser noises were made by tapping a taut pylon line with a hammer, and the lightsaber noises were discovered by accident when a microphone was swung near a TV set (though I could be misremembering some details there, been a while since I read the book about it).
