If the sound waves have a small amplitude,then the sound will be faint.On the other hand if the sound waves have a large amplitude,then the sound will be loud.
The pitch of a sound is directly proportional to its frequency. Sounds of low frequency are said to have low pitch whereas sounds of high frequency are said to have high pitch.
Conclusion :
Amplitude doubled loudnes is also doubled.
Frequency doubled pitch is also doubled.
