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.

-- Two or more astronauts inside the same protective enclosure, such as the International Space Station, or aboard the same vehicle with a 'shirt-sleeve' environment, are able to communicate with each other either by means of the technique known as "talking" or with hand-signals or other 'body language'. -- Astronauts enclosed in space suits may occasionally, if they happen to be close enough, talk to each other by touching the visors of their helmets together, thus establishing a physical medium that can conduct mechanical vibrations of sound between them. -- Two astronauts in any other situation, and any astronaut in communication with Earth-bound facilities at any time and in any situation, must communicate by radio.
