How to make a waterfall more quiet?

[Alon Y amin]

Hi i have a small waterfall that i build in my backyard spilling to my pond.now my

mother saying that sound of falling water is too loud for her and i think its insane because the waterfall have a 0.55 (1ft 921⁄32in) spillway and its only a 0.40 (1ft 33⁄4in) meter tall.
tnyone can give me advice on how to make it more silent but still give air to the water?

Or put something under the water fall so the water doesn't splash.

I picture would help. Slow the flow rate down or like John said put something under the waterfall to control the splash.
