The sound of the bell will become fainter and after some time, the sound will not be heard. This is so because almost all air has been pumped out. This shows that sound needs a material medium to travel.

A bell jar is placed on a base which is vented to a hose fitting that can be connected via a hose to a vacuum pump.
