There are many reasons, but significant ones are related to available atmosphere. The astronauts must stay in their space suits to get breathable air. Denser air is better for the transmition of sound. So it is hard to get sound to go through the space suit and then hard to get it to go through the low density atmosphere of the moon. Radios are easier and can go much farther.

Why did the astronauts have to use radios on the moon?
Since the moon has no atmosphere sound will not travel. An astronaut would need to use a radio to talk to another even if they were only a few feet apart.
Do astronauts use athletic shoes for moon boots?
No.
How does a spacecraft land on moon?
As the gravity is less on the moon, the astronauts use the lunar module.
How did astronauts speak on the moon?
they used radar waves to make it possible to speak on the big blue cheese moon. All astronauts have to use their helmets to do tat
Why do astronauts need radios to talk in space?
Sound is carried by vibrations of molecules. When you talk here on Earth, air molecules transmit the vibrations and allow others to hear you. In open space there are very few molecules at all so there is nothing to carry the vibrations. Radios use radio waves to transmit information from one to another. These waves move through space by themselves so they can be transmitted from one astronaut to another. Then the radio turns the wave back into sound in the air filled compartment the astronauts breath in.

Why do astronauts who land on moon talk through wireless sets using radio waves?
Sound needs air to travel through, and as there's no air on the moon. Astronauts have to use radios to talk to each other when in an envrionment without air. Radio waves travel through space and have no trouble traveling where there's no air.
Can astronauts hear each other?
As there is no air , it is difficult , but astronauts use radios.
Can astronauts speak in space?
Yes, astronauts talk in space, as they always have acess to oxygen.(using radios)
How do astronauts communicate outside the space shuttle?
They use radios built in their space suits.
What do astronauts use to go to the moon?
Space Ships

How do astronauts slow their spacecraft down when approaching the moon?
Astronauts use small bursts from little jets pointed in the direction of travel to slow down the ship when they approach the moon.
What did the astronauts use to collect geological samples on the Moon's surface?
lunar lander
