What term means one complete variation of pressure?

Explanation:
In ultrasound acoustics, one complete variation of pressure is a cycle. It’s one full oscillation of the wave, from maximum compression through zero to maximum rarefaction and back to maximum compression. Amplitude describes how large that pressure change is, not how many times it occurs. Bandwidth is the range of frequencies present, not a single oscillation. Area isn’t related to pressure variation either. If you think in terms of time, the duration of one cycle is the period, but the term for one complete variation itself is cycle.
