Sound waves in air are a combination of dense areas of air particles, called compressions, and 'thinned out' areas called rarefactions. In compressions, air pressure is high because all the particles are in a small space and not moving. In rarefactions, air pressure is low, however the velocity of the particles is high as they are moving very quickly, rushing to the next compression. We can see that sound waves are made of high pressure, low velocity (not moving) parts, and low pressure,...
