Quizplus · Accepted Answer

In space, the lack of air means sound cannot travel as it does on Earth, so astronauts cannot hear each other through the vacuum of space. They use radios to communicate. However, inside a spacecraft with air, sound can travel, but the quality and characteristics of speech might be affected by the spacecraft's atmosphere and pressure conditions.
