Solution

When a tuning fork is struck by a rubber pad and held over a fixed length of the air column in a tube, it creates a loud sound.
Resonance is the phenomenon that causes the above situation.
The unit for measuring loudness is decibel $(d B) .$
Therefore, decibel $(d B)$ , which represents the pressure level of the sound, is a unit for measuring loudness.
