Bell jar experiment can be done to check that sound is a mechanical wave.
Explanation:
Mechanical wave is that wave that can not travel in a vacuum where there is no matter unlike transverse wave. Transverse are perpendicular to the direction of sound and travel through vacuum too.
Bell jar is an equipment which is used to create a vacuum. Using this vacuum we can find that sound wave can travel in it or not.
We can not hear the sound from another end of the equipment as there is a vacuum between the source and the observer.
