I tripped across this website from a weather site ad with an excellent explanation on pump cavitation. Where I worked there was a 3HP irrigation pump that always had this issue. The solution was to restrict the 2" out flow pipe with a ball valve partially closed. You will hear it on pool pumps especially when it it is self priming on start up. At first you think the pump is ready to blow apart then it smooths out. This article shows examples of commercial pumps applications but the noise is similar to any pump.
