Answer

The amplitude in a sound wave is the maximum pressure of the air in a compression.

Work Step by Step

The amplitude of any periodic variable is related to how much it changes over a complete period. A sound wave's amplitude usually refers to the maximum variation in the air pressure, as stated on page 394. However, it should be noted that in a longitudinal wave, such as sound, sometimes "amplitude" refers to the maximum physical displacement of particles.
