Hi Jo. Yes, the water running down the stone ball makes a sound. However, the amount of noise depends on the pump size. If you're keen to hear the water, a less smooth surface might suit you more. This is a picture of a slate water feature I designed and built in Perthshire, Scotland. The sphere is made of stacked round circles of slate that form the ball. Hope this helps. James

All very good informative advice, thank you. Popped into your beautiful shop the last week, stunning flowers!

Thanks Jo, you're very welcome! Don't hesitate to contact me if you need any advice with the water feature. James
