Usually, people are asking as if there is just "the" amplitude in sound waves in air.
The loudness perception of a sound is determined by the amplitude of the sound waves −
the higher the amplitude, the louder the sound.
Which amplitude of sound (sound amplitude) do you mean?
There are:
amplitude of particle displacement ξ, or displacement amplitude
amplitude of sound pressure p or pressure amplitude
amplitude of sound particle velocity v, or particle velocity amplitude
amplitude of pressure gradient Δ p, or pressure gradient amplitude.
Furthermore, think of the amplitude of the oscillation of a string.
The maximum magnitude of the deflection of a wave is called amplitude.

What does the amplitude of a wave depend on?
In the case of sound, amplitude is related to volume or loudness.- loud sounds generate waves of larger amplitude and your ear would register sound waves of large amplitude as louder.
How can the loudness of a sound be determined by the waves?
The loudness of a sound (or intensity) corresponds to the sound wave's amplitude. The amplitude of a wave is the distance from the midpoint of the wave to a high-point (crest) or low-point (trough).
What are the two properties of sound waves that you use to classify different sounds?
The two properties are :- Pitch & Amplitude
What does amplitude of a sound wave determine?
Amplitude is the volume of the sound in sound waves. The higher the Amplitude, the louder is the sound. Sound waves are pressure or compression waves in the material through which the sound is traveling. The pressure or compression waves also result in small longitudinal displacements of the atoms or molecules. The amplitude of the sound wave determines the range of variation of pressure, compression, or displacement.

Loudness.

If a band is playing loudly will the amplitude of the sound waves be small or large?
The amplitude of the sound waves will be largerbecause the larger the amplitude the louderthe sound.

What property of sound waves is related to the amplitude of the waves?
Loudness.
What affects absolute brightness?
Brightness corresponds to amplitude of waves. Greater amplitude means greater brightness (so lower amplitude means less brightness).
Is the loudness of the sound its waves amplitude?
Yes.
What is intensity as it relates to sound waves?
Amplitude.
Which of these associated with the loudness of sound waves?
Amplitude
What is an amplitude in sound?
Amplitude of a sound wave is the height between the peak (top most part of the wave) and the trough (bottom most part of the wave). So as the wave travels, say on a string, the highest the string or wave moves up minus the lowest the string or wave moves down is the "amplitude" of the wave.
What does amplitude measure?
Sound energy travels in waves and is measured in frequency and amplitude
