How do you make a quiet (from splashing) waterfall

[lone ranger]

I am a designer (not engineer). I am trying to develop a quiet waterfall, or fountain. That is, that the water that falls into the pool, doesn't make a splashing noise. The falling water must fall into a pool of water, not onto a solid surface. Anyone have Ideas of how to make such a thing? Possibly adding something to the water, or some other Idea.
Thanks

Can you arrange that the water flows as a laminar flow (ie a smooth flow) into the water rather than droplets?

Thanks for the reply. I don't completely follow what laminar flow is, other than the drops don't separate, and flow in a solid form, nor do I have any Idea how to make a laminar flow happen. However I am quite sure that this is not the visual affect that I want from the fountain. The fall is to look more like the natural waterfall , with random flow.

Laminar flow just means smooth, like how a tap flows as a single unbroken stream of water before it breaks up into drops.
If you want it to look like a moving waterfall you could try breaking up the surface where the water hits the pool with air bubbles from something like an aquarium air block + pump.
You aren't going to make a large waterfall totally quiet though

Why would air bubble in the water make it more quiet?

The idea is that the drops hititng a broken surface or water covered air bubbles would be quieter than the slap of a drop onto a flat surface.
Just a guess really.

It makes good sense. I'm wondering, too, if something like glycerine might help.
