Loudness

Louder sounds are produced by sound waves of higher amplitude let's try to visualize it we need a metal glass and spoon for some water limited class now strike the glass with a spoon and observe the sound first softly then a little harder and again very hard you observe that the loudest sound is produced when the glass is struck the hardest now we will test the amplitude of the sound waves keep the glass near the term called ball which is hanging from a string let the ball slightly touch the glass now again strike the glass and observe the ball we see that the term called ball gets this page more and the glass is struck harder this shows that the glass vibrates with more amplitude minute strike harder so we can send you the difference and loudness of sound is due to difference in the amplitude of waves it produces.
