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 do astronaunts on the moon have to communnicate by radio even when close to one another?
Sound needs a medium to be transmitted in ... when we hear a sound it's just moving air. The air moves on our eardrums and THAT is how we hear .. on the moon there's basically no air for the sound to travel in .... .... it would be possible for astronauts on the moon to touch their helmets together and talk that way, if for example their radio was not working. ____________________________________________ They don't. Sound carries from the astronaut's mouth to his helmet, and if two astronauts were to touch their helmets together, the sound would be carried clearly to the second astronaut. However, if they are not actually touching helmets, the sound cannot be transferred through the vacuum of space. In that case, they would need to use either radio or some visual means of communication; visual hand signals, or a laser link, something like that. Or, for medium range verbal communication in space, you could use a version of the "two tin cans and a string" telephone. Attach a wire from one helmet to the other, and pull away so there is some tension in the string. Speak normally. The vibrations of the air inside your helmet will cause a vibration in the string. The vibration in the string will cause vibration in other helmet, and you will be able to hear. Not as well as a radio, and not as clearly - but it will work.
