Can you hear your own voice in a vacuum?

No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.

Can humans hear their own voice?

While some of the sound is transmitted through air conduction, much of the sound is internally conducted directly through your skull bones. When you hear your own voice when you speak, it’s due to a blend of both external and internal conduction, and internal bone conduction appears to boost the lower frequencies.

Can we hear our original voice?

You are the only person that ever hears that voice.” But there is another way for the sound of your own voice to reach the cochlea and for you to hear it: through the bones in your head. As you speak, your vocal chords are vibrating, which in turn vibrates your entire skull.

Can you scream in a vacuum?

A: Sound is a mecanical wave, which means that it needs substance to travel through, such as air or water. In space, there is no air, so sound has nothing to travel through. If someone were to scream in space, the sound wouldn’t even leave their mouths.

Can you hear someone talking in space?

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise.
