Scream Fountain: As a new type of water feature entertainment, it operates by converting the pitch and duration of human voice into analog voltage to control the frequency of the variable-frequency drive. Adjusting the frequency alters the motor speed, which in turn modifies the pump pressure. This allows for controlling the pump speed, adjusting the water flow rate, and thus changing the height and duration of the fountain's spray. It is an engaging and aesthetically pleasing water feature project.
