Sound Wave as a Longitudinal Wave.
(A bomb impulse wave is usually omni-directional or all directions.)
In energy science we usually try to transfer energy efficiently in a direction.
A sound wave is a series of compression and rarefaction of layers of air molecules repeatedly through space.
The speaker gives an impulse or series of impulses. The diaphragm swats the air particles in a guided direction. This is Direction of motion.
Because the direction of motion of air particles in the wave is parallel to the direction of movement of the speaker diaphragm it is longitudinal.
The forward and backward vibration of the air molecules within the sound wave have the attributes of rarefaction and compression.
Regardless of the back and forth vibration within the wave there is a direction of motion of the wave.
The cone of the speaker guides the wave a direction. This is called unidirectional.
