Which term describes the maximum value of a sound beam's intensity?

Explanation:
When a sound beam is pulsed, its intensity rises and falls over time at any point in space. The highest value it reaches at any moment during the pulse is the peak intensity. This is the maximum instantaneous strength of the beam. The other terms describe different ways of averaging or describing the beam: average intensity is the mean value over time, temporal refers to the time aspect (not a value itself), and pulse refers to the burst duration rather than its maximum strength. So the term that names the maximum intensity is peak.
