SUMMARY
The audible sound in the fountain video is primarily caused by the instability of the valve controlling the water flow. This phenomenon occurs when the design of the valve allows for a pressure drop that intermittently pulls the valve closed, followed by an increase in pressure that causes the valve to reopen. This cyclical process results in vibrations that produce sound. Similar effects are observed in hydraulic power steering systems, particularly at low vehicle speeds, leading to a condition known as "steering shudder."
