Underwater Sound Effect
Tap to play the underwater sound.
The underwater sound effect is a muffled, bubbling ambience of being deep below the surface. People play it in the background for relaxation and focus, and editors use it for diving scenes and sinking jokes.
Play It on a Soundboard
The underwater sound is also on the Nature Sounds, next to similar sounds you can tap one after another. To make a board of your own picks, use My Soundboard.
