Question

Define loudness of sound​

Answer 1

Answer:

The loudness of a sound relates the intensity of any given sound to the intensity at the threshold of hearing. It is measured in decibels (dB).

Answer 2

Loudness is proportional to the square of the amplitude of the vibration body producing sound. The more the amplitude of vibration, the sound is the loud. The lesser the amplitude of vibration, the sound is feeble.
