The term for a traveling variation of acoustic variables is?

Explanation:
A traveling variation of acoustic variables is called sound. In ultrasound, pressure, density, and particle velocity fluctuate as waves move through a medium. When these oscillations propagate away from the source, they form a sound (or sound wave). The other terms describe different ideas: temporal relates to time, spatial to space, and spatial pulse length is the physical length of a pulse, not the traveling disturbance itself.
