There's no sound in space because sound is vibration through a medium, such as air or water. For a long time people thought there must be a medium they called aether in space for light waves to travel through, but as it turns out, light (actually all electromagnetic radiation, including radio and gamma rays) doesn't need a medium. So in a way you CAN "hear" from space when EM radiation is converted into sound by electronic devices.
No as there is no air in space sound can not travel so they use radios.

Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
Why can astronauts hear on moon if they come close to each other so that their helmets touch?
Normally, to communicate in space, astronauts need radios. This is because sound (in this case, speech) requires a medium (such as air) to move through. In space, since there is no air, astronauts cannot talk to one another directly. However, in your case, the astronauts may converse because their helmets are touching - thus giving the sound waves a medium to move through - the helmets.
Why can astronauts not talk to each other without communication equipment on the moon?
There is no air on the moon. Sound waves only propagate through a medium, such as air, water, etc. Sound waves cannot propagate through a vacuum, therefore the astronauts had to use radios to speak to each other.
Do astronauts sleep in outer space?
Yes. Extra Fact: When in space, no one can hear you scream.
Do shuttle astronauts cease to hear engine thrust sounds once the shuttle and rockets exceed the speed of sound?
yes
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
What do ashronauts hear in space?
In space, astronauts do not hear sound as we do on Earth because there is no air to transmit sound waves. However, they can communicate with each other and with Mission Control using radios and headphones inside their helmets. They may also hear vibrations transmitted through their spacecraft.
Astronauts on a space walk cannot hear each other. Why?
They can not hear each other through the natural environment due to there being no medium for the sound waves to travel through. However, they can hear each other through the use of radio communication.
Why astronauts cannot hear each other in space?
Space is vacuum, and sound can't travel in vacuum.
Can you hear can you hear through space suits?
Indeed! You can't hear what's going on around you, but you can hear other astronauts through their radio.
Why can 2 astronauts on a spacewalk see each other but not hear each other without radios?
Since there is no air, the sound waves would not travel. Radio waves being electromagnetic do not rely on matter (atmosphere) to conduct them.
Why Do astronauts cannot hear each other on the moon?
Astronauts cannot hear each other on the moon due to the lack of air and atmosphere, which are necessary for sound to travel. Sound waves need a medium to propagate, and in the vacuum of space, there is no medium for sound to travel through. While astronauts can communicate through radios inside their helmets, they cannot rely on sound to transmit through the lunar environment.
Why is it when 2 astronauts have their helmets touching they can hear each other why?
When astronauts touch their helmets, sound vibrations can travel through the material and air between the helmets, allowing them to hear each other. This method of sound conduction is known as bone conduction and helps transmit vibrations directly through solid surfaces, like the helmets, bypassing the need for air as a medium for sound.
Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
Can you hear any sounds in space?
In space, sound does not travel because it is a vacuum, meaning there are no molecules to carry sound waves. Astronauts can communicate using radio transmissions inside their spacecraft, but they cannot hear sound like we do on Earth as there is no medium for sound to travel through in outer space.

To hear astronauts in space the sounds waves are converted to?
