Question

What characteristics of sound would change if there is a change in its amplitude and wave form

Answer 1

Sound is a form of energy which gives us sensation of hearing.

a]If amplitude of sound wave changes then Loudness changes.

The loudness of sound depends upon amplitude of sound wave.
If amplitude is more then sound is loud.
It is expressed in decibel [dB]

b]If wave form changes then it effects its pitch
The pith of sound depends on the frequency of vibration.If frequency of vibration is higher than we say sound is shrill.

Answer 2

Answer: He'll your answer is below

If amplitude change then loudness changes and if wave form changes then it effects it's pitch
