Why astronauts cannot hear each other in space?

Space is vacuum, and sound can't travel in vacuum.


Will astronauts hear each other if their helmets are touching?

Yes, astronauts can hear each other if their helmets are touching because sound can be transmitted through solid materials. When their helmets make contact, vibrations can travel through the helmet material, allowing sound waves to pass between them. However, in the vacuum of space, they would not be able to hear each other through the air, as sound cannot travel in a vacuum.


Why can astronauts hear each others voices when their helmets are touching?

Astronauts can hear each other's voices when their helmets are touching because sound can be transmitted through solid materials, such as the helmet's surfaces. When one astronaut speaks, the vibrations of their voice travel through the helmet and into the other astronaut's helmet, allowing them to hear each other despite the vacuum of space surrounding them. This method of sound transmission is similar to how people can hear each other when they are connected by a solid object, like a wall.


How do astronauts hear each other when they touch helmets?

Astronauts can hear each other when they touch helmets because their spacesuits are equipped with communication systems that include microphones and earpieces, allowing them to transmit and receive sound even in the vacuum of space. When helmets make contact, the vibrations from their voices can also travel through the material of the helmets, enabling them to hear each other more clearly. This combination of technology and physical contact allows for effective communication in the challenging environment of space.


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.

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.

As there is no air , it is difficult , but astronauts use radios.

Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)

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 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.


When two men walk in moon they cannot hear each other why?

Because there's no air ! They have to communicate by radio.


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.
