If sound cannot travel in a vacuum, why is my vacuum cleaner so damn loud?

Earth Janitor, Imagine all the space battle scenes in Star Wars being completely silent. Wouldn't have been such good viewing would it?

Mitrilys, Science astronomers say we pick up sound signals from far away stars and galaxies! Maybe the sound carries through a vacuum, but is unable to be heard until it reaches a substantial medium for it to be heard!

no, it will travel through the beam! kind of like the telegraph, or the older style telephone wire poles! You spoke into a transmitter, carried through the wires, and heard on the receiver!

SpaceMan626, unless the sound was generated inside the cockpits which would have had to hold an oxygen like medium for the pilots!

Shonkatron, silence in space worked in "2001: A Space Odyssey" because of the music. I'm sure John Williams could have handled it.

Earth Janitor, thank you! Sound in outer space has always been a cinematic pet peeve of mine.

Greyghost 68, that’s why I don’t understand this question. I thought all sounds travel.

if you put a metal beam in a vacuum and connect it to a sound source, the sound will travel through the vacuum? 😬

Fun fact, since space is not a perfect vacuum, some sounds can still travel there. But regular humans can't hear them.

TwoTin16, don't think it travels faster, just that we can hear better as less background noise, or silence.
