The amplitude of a sound is its intensity or loudness. The amplitude of a sound wave is measured in decibels (dB). The higher the dB, the louder the sound.

There are a few ways to represent the amplitude of a sound. One way is to use a sound level meter. This is a device that measures the dB of a sound. Another way to represent the amplitude of a sound is to use a graph. This graph will show the amplitude of a sound over time.
