Question

explain why some sounds are feeble and some are loud​

Answer 1

${ \underbrace \text \red{answer}}$

The loudness of sound depends on its amplitude. When the amplitude of vibration is large, the sound produced is loud. When the amplitude is small, the sound produced is feeble. ... If the frequency of vibration is lower, we say that the sound has a lower pitch.
