Gurgling Water Nature Sounds. Gurgling Water: The feeling of lying next to a small stream with water running over rocks creating gurgling and light splashing sounds. Mid-range sound masking makes the water noise effective for covering up a wide range of ambient sounds. A great soothing and relaxing sleep aid. Put on your favorite set of headphones or earbuds, sit back and relax in your recliner or sofa, and let time pass in your state of total relaxation.
