LDi PulseView pipe system software models are designed and compiled to determine the response of valve members, membranes, & moving components to the excitations caused by variations in velocity of liquid mass. The plots are what you see from linear transducers connected to moving parts & pressure transducers through holes into valve inlet and outlet pockets.
Pressure Pulsation Modeling and Analysis
Pressure pulsation caused by component and liquid mass movements.
This is not "acoustic" guesswork.
All Plots are on the same time scale
Resultant Pressure behavior
