Amplitude is the strength or height of a sound wave, reflecting how much the air particles are moved by the wave. When a wave has greater amplitude, the pressure variations are larger, and the sound is perceived as louder; smaller amplitude means quieter sound. It’s measured as the maximum displacement from rest (peak height) and is distinct from frequency (how often the wave repeats per second, related to pitch), the shape of the waveform (the exact pattern of the wave), and duration (how long the sound lasts).
