Detailed Solution

The above statement is True.
Vibration is needed for sound production, and various methods can obtain this vibration. For example, they start vibrating and producing sound when the two bodies strike. An important property needed for producing sound is that the vibration frequency should be the same. Therefore, the sound produced by the vibrating body will be heard by us when it is in the audible range. However, only some frequencies can be heard with the human ear. For example, frequencies between

20 Hz

and

2000 Hz

only can be heard. Therefore we cannot hear every sound of a few vibrations.
Therefore, it is true that vibration is necessary for producing sound, but we cannot hear the sound produced by every vibrating body.
