Vibration is nothing but movement of the source in a sinusoidal manner. When the source moves, it pushes the medium it is immersed in (usually air). If not on vacuum, the "pushing" of the medium propagates as pressure waves according to the medium's physical properties (speed of sound in the medium). If those waves are in hearing range (from 300 to ~22000Hz) we call them sound. | |

Or is it the medium that according to the source movement will be affected (at that instant) which will cause a difference in the response to the vibrations? – maha 41 mins ago | |
