Sound is mechanical energy, and the energy of the sound is transferred into the medium through which it is travelling. As the energy of sound is carried by the medium, the vacuum of space will not support a sound wave.

∙ 10y agoIf their is air in the jar, you should be able to hear the bell ringing. Air carries the sound waves from the bell to the jar and to outside the jar so that the ringing is heard. Without any gas media in the jar, the sound would not be carried to the outside and the bell would not be heard.

What can you hear when a bell rings in a vacuum?
No sound. Beacuse sound need air to travel..
Experiment to demonstrate that sound need a material medium to propagate?
Take an electric bell and hang this bell inside an empty bell-jar fitted with a vacuum pump (as shown in the following figure). Initially, one can hear the sound of the ringing bell. Now, pump out some air from the bell-jar using the vacuum pump. It will be observed that the sound of the ringing bell decreases. If one keeps on pumping the air out of the bell-jar, then at one point, the glass-jar will be devoid of any air. At this moment, no sound can be heard from the ringing bell although one can see that the prong of the bell is still vibrating. When there is no air present inside, we can say that a vacuum is produced. Sound cannot travel through vacuum. This shows that sound needs a material medium for its propagation.
Why a bell ringing inside a vacuum chamber cannot be heard?
sound needs a medium to travel. material medium is necessary for propogation of sound. in vaccum sound do not travel. that's the reason why we are not able to hear sound in this case. Jordi101
What are the jobs in the bell jar experiment for the foam block and vacuum pump?
The vacuum pump stops the sound waves from coming out. Because there are no particles to pass on the sound in a vacuum, we see the clock vibrating, but do not hear anything at all.
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.

Why cant we hear each other on the moon?
The Moon has no atmosphere, only vacuum. There is nothing for the sound waves to travel in.

If a bell is ringing in a bell jar you cant hear it when the air is pumped out but you see it what differences in properties of sound and light does this indicate?
That sound cannot move through a vaccum.
In the game club penguin how do you turn the sound on to hear the conversation inside the closet?
you cant
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.
Vacuum booster requires too much pedal effort?
Either it is not getting enough vacuum or the booster is going bad. You can sometime hear a whistle inside under the dash if it is leaking.
Why No air from ac vents?
first check all fuses related to the AC system. i think there are 3. if you can hear the blower motor from inside the car when the air is on, it is most likely the vacuum line from the intake manifold is off or broken. it is the rearleft most line coming off the manifold if looking from the front of the car. if you cant hear the blower motor, either the switch or blower motor are bad. it is most likely the fuse or vacuum hose though.
Sounds of airplane?
The sound of the airplane from the outside is pretty loud BUT when you get inside of an airplane and your flying you cant hear any thing
What do people hear when they hear the liberty bell?
People hear nothing because it is no longer rung. The Liberty Bell is an actual bell. It was last rung on February 23, 1846. It is cracked and can no longer be rung.
