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)
It doesn't travel at all. Sound needs something to travel in, atmosphere, liquid, or solid - but space is vacuum. Hence no speed for sound in space.
waves of pressure, kind of like ripples in a pond
Sound does not travel in space, there is no sound at all. Sound need air to vibrate, that is all sound is, vibrations. there is nothing in space, so no sound.
A sound wave traveling fast and slow depends if it is traveling through a solid, liquid or gas.
Going to the opposite end of the planet through the air would take about 16 hours at 340 meters per second.
Going through the ground, at about 5 km/s, would take about 45 minutes.
It travels at the speed of 300
Very fast
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.

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.
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
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.
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.
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.
In outer space there is no air medium for travelling of sound waves.so it is impossible for sound to travel through outer space ..!!
sound waves can't travel in a vacuum (space)
Space is a vacuum. Sound cannot travel in vacuum
There is no sound in space.
Nope, sounds doesn't travel faster on space because a medium is needed a region to another
Sound can travel on the moon because there is no atmosphere. Space is a vacuum that does not allow sound to travel.
If you're referring to outer space, then sound does not travel at all.
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.
Sound cannot travel in empty space. But, sound may be able to travel through your body.
No. Sound is the vibration of air. Sound will not travel in a vacuum. Space is a vacuum
sound cannot travel through empty space.
