Sound in space?

hi /sci/,

If I was in space, and something was making a noise, would I hear it?

No, you would be dead.

In space, there is no physical medium to carry pressure waves to express sound.  In cases where there ARE physical media to carry waves of pressure that you can detect, those media and waves will be produced together, and those waves are almost certainly of such huge amplitude (like a nova explosion) that you wouldn't survive anyway.  So, the implied Q&A is:

Q. What does a supernova sound like?
A. It sounds like you're dead.

It depends on whether there's a transmission path from the sound source to your eardrum through a physical medium, and whether the physical medium will dampen the vibrations to below your hearing treshold.
So the answer varies based on where and when in space you and your sound source is located. Other factors may also play in, like how loud the noise is, or if you're deaf.

When particles impact your spacecraft you can hear them.

That makes no sense. I don't even have a spacecraft.

Oh man, you should get one; they are wicked awesome

I would like you better if you would remain anonymous, but yes. /thread.

Now let's talk about spacecraft. Would you go for ion propulsion? Is a Bussard ramjet at all feasible? And why won't Einstein leave us freaks with a need for speed alone?

A spacecraft is filled with air, no? So that situation is a tautology; hearing sound in a spacecraft is just as amazing as hearing sound on Earth.

Best comment ever.

Not necessarily. You could have one of the cheap models where you have to wear your oxygen mask and pressure suit while onboard. It could even be more of a space scooter.

...Well, then you wouldn't hear any particles hitting the spacecraft, would you?
