A sound wave needs a medium to travel
A sound wave travels in the form of a longitudinal wave and it requires a material medium for its propagation. Sound always originates from some vibrating body. These vibrations are produced by tuning forks, drums, bells, the strings of a guitar, etc.
Human voice originates from the vibrations of the vocal chords and the sound from the musical instruments is due to the vibrations of the air columns. In some cases, the vibrating frequency of the source may be so very small or so very large that it is not audible to the human ear. The audible frequency ranges from 20 Hz to 20 kHz. The frequency below 20 Hz is called infrasonic and the frequency above 20 kHz is called ultrasonic.
The bell jar experiment is a common experiment used to demonstrate that sound needs a medium to travel.
