In SI units with dry air at 20 °C (68 °F), the speed of sound c = 343 m/s.
This also equates to 1235 km/h, 767 mph, or 1125 ft/s.
In space, contrary to the popular myth, there ARE sound waves and these propagate at roughly 300 km/s, depending on density and pressure.
Just because we can't hear it, that's a fact, that does not mean that sound waves do not exist. (the same exciting frequencies will propagate faster, being further apart in rarer mediums, longer wavelengths)
What else can I help you with?
Why cant sound travel through outer space?
Sounds requires a medium to travel through. An example is air. You've also heard sound travel through water and solid objects like wood. In the past it was often thought that no medium exists in space. However, in current astronomy and astrophysics it is thought that dark matter is the medium by which sound can and does travel about space. Due to the atoms being so spread out though, the human ear would not be capable of detecting the sound waves.

What types of materials can sound not travel through?
Spongy materials are the most difficult for sound to travel through. Vacuum is the best acoustic insulation but it doesn't really count for the purpose of this question, since it is not a material but a lack of material.
What factors are necessary for a sound wave to travel through a medium?
well sound actually always needs a medium so it can travel, in space there's is no sound because there isn't a medium it can travel through. but just about anything is a medium for sound. air is also a great medium, that's why were able to hear one another
Why can light travel through space but sound cannot?
sound is produced by vibration, i.e. when any thing start vibration then it produces sound. for example when a tunnig fork is hit on rubber pad its prongs starts vibration with difinit frequency ad hence produce sound. similarly when the strings of a gittar is dirturbed its starts vibration and hence produces sound. sound required a material medium for their journey, sound can not pass through vaccume because sound waves are mechanical waves.
Why does sound not travel through space?
Sound does move through space. It doesn't move though empty space, i.e. a vaccuum. In outer space there is a vaccuum (though not necessarily a perfect vaccuum).Sound is caused by vibrations in a medium such as air (or water or wood). These vibrations compress and rarefy the medium. The vibrations move through the medium as waves.In a vaccuum, there is no medium thus there is no sound.
Why is it impossible for sound to travel through outer space?
Sound requires a medium, such as air, water, or solid surfaces, to travel through. In outer space, there is no medium for sound waves to travel through, so sound cannot propagate in the vacuum of space.
How far can sound travel in space between astonauts?
Sound waves require a medium to travel through to propagate from point A to point B. In space there is no such medium, so sound does not travel in space.
What can sound waves not travel in?
sound waves can't travel in a vacuum (space)
How long does it take for sound to travel one mile in space?
There is no sound in space.
Can sound travle to space?
Space is a vacuum. Sound cannot travel in vacuum
Why cant sound travel on the moon?
Sound can travel on the moon because there is no atmosphere. Space is a vacuum that does not allow sound to travel.
How far will sound travel through space in 1 second?
If you're referring to outer space, then sound does not travel at all.
Does sound travel outside the earths atmosphere in space?
No. Sound is simply vibrations of particles that travel in a sort of "wave" motion. Since there is no medium (particles of matter) in space, it is not possible for there to be sound.Sound waves require a medium to travel through. They travel by knocking particles into other particles, causing a vibration to be transmitted.As outer-space is a vacuum, there is no matter present; this means that there is no medium for sound waves to travel through. Therefore, sound cannot travel in space.
How do you hear yourself in space without a space suit?
Sound cannot travel in empty space. But, sound may be able to travel through your body.
Can people here sound in space?
No. Sound is the vibration of air. Sound will not travel in a vacuum. Space is a vacuum
What type of material can travel through space?
Sound and Light can travel through space.
Why cant sound trave through empty space?
Sound requires a medium, such as air or water, to travel through. In the absence of a medium, such as in empty space, there are no particles for sound waves to propagate through, so sound cannot travel.
