The sound of moving water is very soothing. It helps to create a more natural feeling surrounding, and can help people to relax. The sound of moving water can be a background white noise that blocks or reduces other background noises, helping people to concentrate. Alternatively, it can be a much more subtle trickling sound.

The sound of moving water can be provided both indoors and outdoors, through the use of fountains, water walls or artificial waterfalls.
