Sound relies on particles of matter to transfer its energy. For instance, when you speak, that sound wave travels through the air particles, pushing each one towards the next with the message of sound to the ear of another person for example. Even in water, sound does travel, but it's harder to hear because water is so dense.
In a vacuum, there is no air, so no air particles to carry the sound, and thus, no sound can be heard.

What do you hear when an alarm clock rings in a vacuum?
Nothing! Sound is wave and needs a medium to pass through in order to be heard !!!Nothing, because sound cannot travel in a vacuum.
What are the properties and behavior of sound waves in a vacuum?
Sound cannot exist in a vacuum, as sound is the vibration though a substance, known as the medium. If no medium is present, no sound is transmitted. In a vacuum, there are no or too few air molecules, that means there is no medium for the sound to exist in, thus there is no sound. It is also why you cannot hear much in space, as the molecules or individual atoms in space are so far apart.
Can you hear in a vacuum?
No. Since there is no air in a vacuum and sound travels only with the presence of air, you can't hear in a vacuum.
How fast is the speed of sound in a vacuum?
Sound waves cannot travel in a vacuum.
How fast can sound travel through a vacuum?
Sound cannot travel through a vacuum.
Why astronauts cannot hear each other in space?
Space is vacuum, and sound can't travel in vacuum.
Why can't we hear nuclear explosions from the sun?
We cannot hear the explosions from the sun as sound cannot travel through a vacuum, and the sound would have to travel through one to reach the Earth.
Would astronauts be able to hear an explosion on the moon?
no, sound cannot travel to the vacuum of space
Why do we not hear the suns nuclear reactions?
Simply because - sound cannot travel in the vacuum of space.
Why can't you hear any sound from space?
Space is a Vacuum, consequently there are no atoms/particles to pass on the vibration a sound makes, so the sound cannot travel, and this is because space is a Vacuum.
Can people can talk on moon and other people there can hear them?
because there is no sound in space and sound cannot travel through vacuum

Why can we see light from the sunbut not hear the explosions from the sun?
Between the earth and the sun there is no air (its a vacuum). Sound cannot travel across a vacuum. Light can.
If a tree fell in a vacuum why wouldn't you hear a sound?
Sound does not travel through a vacuum.
Can you hear in a vacuum?
No. Since there is no air in a vacuum and sound travels only with the presence of air, you can't hear in a vacuum.
If a satellite or spaceship explodes in outer space you can see the explosion from a distance but why can you not hear it?
Light travels in vacuum but sound cannot. So, we can see solar flares but can't hear them. (Outer space can be considered to be vacuum)
