Glen Burnie waterfalls that drown out BWI flight paths
Sound masking is about volume and spread. A wide, low fall over flat stone makes a soft hiss that fills the patio. A narrow, tall drop makes a sharper splash you hear across the yard. We set the drop height and flow during the first test run and adjust it with you sitting where you normally sit.
A backyard waterfall installation aimed at noise goes close to the seating, between you and the flight path, not out by the back fence where it looks nice and does nothing.
