Waterfall Height
There are some types of sounds, created by on what water falls.
The sound may be produced when water falling directly to a water surface or falling on a rocks and then sliding down on stones.
The waterfall height s most important factor. Lower to 5” to 6” may little decrease sounds but as increased to 20″ – to 30”, sound increases are considerable. From all factors while building backyard waterfalls, height is the most clear to understand.
