Answer:

Astronauts wear communication devices called intercoms on the ear.

Step-by-step explanation:

We know that the outer space is a vacuum environment and hence sound waves cannot travel through space. Hence an alternative means of communication is necessary for proper communication between two astronauts. This alternative is the use of intercom. Its functioning is similar to a walkie-talkie, it transmits and recieves radio waves for communication
