There is not only "one" amplitude.
There is an amplitude of particle displacement ξ, or displacement amplitude,
an amplitude of sound pressure p or pressure amplitude,
an amplitude of sound particle velocity v, or particle velocity amplitude,
an amplitude of pressure gradient Δ p, or pressure gradient amplitude.
If the "sound" inceases, the "amplitude" also increases.
sound waves are made by amplitudes
The amplitude of sound waves can vary, from small amplitudes for quieter sounds to large amplitudes for louder sounds. Volume is typically perceived as being louder with larger amplitudes.
Sound is the compression of molecules and atoms in waves which can have different frequencies amplitudes and wavelengths that determine how we interpret the sound.
Waves with larger amplitudes typically sound louder. Greater amplitude results in more energy being transferred to the air, creating louder sound waves. Lower amplitude waves usually sound quieter.
sounds waves are longitudinal and mechanical waves
Two sound waves with the same frequency but different amplitudes can be heard when comparing a soft whisper and a loud shout. Both have the same pitch (frequency) but differ in volume (amplitude). Another example could be a gentle tap on a drum compared to a hard strike on the same drum, producing sound waves with the same frequency but different amplitudes.

A series of vibrations that can be heard is called sound waves. These waves travel through a medium, such as air or water, and are perceived by the auditory system as sound. Sound waves can have different frequencies and amplitudes, which determine characteristics like pitch and volume.
Interference of waves occurs when two or more waves meet and overlap in the same medium, leading to the superposition of their amplitudes. This phenomenon can manifest as constructive interference, where wave amplitudes add up to produce a larger amplitude, or destructive interference, where wave amplitudes cancel each other out. Interference is commonly observed in a variety of wave systems, such as sound waves, light waves, and water waves.
When the amplitudes of waves are equal, waves with higher frequencies have more energy. This is because energy is directly proportional to frequency for waves with the same amplitude.
