Amplitude is a measure of the size of sound waves. It depends on the amount of energy that started the waves. Greater amplitude waves have more energy and greater intensity, so they sound louder. As sound waves travel farther from their source, the more spread out their energy becomes.

Decibells, the more decibells the louder the sound is, the lesser decibells the softer the sound is.
What common unit is used to measures sound intensity?
Sound is measured in decibels, dB. Ten decibels (one Bel) sounds twice as loud as another sound. One decibel is the amount of sound just distinguishably louder than another sound. Named after A G Bell of telephone fame.
How does amplitude affect the loudness of a sound?
it is how loud the sound is ^Smartass comment. The real answer: Loudness is determined by the intensity of sound waves.
Which two properties of a sound wave change when a sound gets louder?
It was when the air hit the wave and it move to another direction
