"In space," some marketing genius once said, "no one can hear you scream". Bring the Xenomorph and its associated ecosystem back home, however — as "Alien: Earth" so memorably has — and you hear absolutely everything… whether you want to or not.
The best sci-fi has always had great sound design, whether it’s the famous piano string-scrape of a TARDIS materializing (eloquently described as a "Vworp" by numerous "Doctor Who" comic strips) or the satisfying beeps and whistles of the USS Enterprise bridge. The aural treats of a galaxy far, far away — from hyperdrives and lightsabers, to Rancors and R2 units — are so plentiful that there is literally a book about them (called, appropriately enough, "The Sounds of 'Star Wars'").
