Why Can Spring Water Make Noise?

Sound or noise comes from the vibration of objects. When water vibrates, it also makes noise. Different water vibration makes different noises.

When the spring water falls down from a higher place, it falls down with part of the air. In the spring water, the air becomes water bubbles. When these bubbles break, they make noise. At the same time, when the spring water touches stones or tree branches, it also makes noise. If a spring is beside a mountain cliff or in a cave, you can hear the echo of the failing drops of water.
