We call that type of wave longitudinal, like this:But people show sound as "up-down" waves because it is easier to show that way.Audio SpectrumA low frequency of vibration has a low pitch and makes a deep sound, like a growl.

Thus, no phenomena such as turbulence, boundary layers, or shear waves are encountered in an inviscid fluid. Suppose that the source transmits a signal with a time signature f(t), then the source function may be expressed as (2.19)Q=Sf(t). In this case, the wave equation in Eq. (...
A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water or any other liquid orsolidmatter) as it propagates away from the source of the sound. Sound waves are created by object vibrations and producepressure waves, for exam...
