\nThe amplitude of sound waves is measured in the units of pressure.
\n<\/section>\n
\nSound waves in a medium like air are longitudinal waves involving compressions and rarefactions. The amplitude of a sound wave is the maximum variation in pressure from the equilibrium pressure (atmospheric pressure) or the maximum displacement of particles from their mean position.
\n<\/section>\n
\nWhile amplitude can be expressed as displacement amplitude (measured in meters, a unit of distance), it is more commonly and directly related to the intensity or loudness of the sound when expressed as pressure amplitude. Pressure is measured in Pascals (Pa), which are units of pressure. The options provided include both pressure and distance, but pressure is a more direct measure of the force per unit area variation that constitutes the wave, and its amplitude correlates directly with loudness.
