This example shows the creation of a sonic wall, or fence, in a park landscape. The sonic fence emits an alarming sound whenever the user steps outside the green circular sound element. This sonic fence can be deactivated by locating the hidden switch, depicted by the blue circular sound element. The latter can be found by following the ambient soundscape (the red circular sound element) that increases in volume as the user approaches the location of the switch.
In the first part of the video, the creation of the soundscape is shown, while in the second the simulator mode is used to test how it would sound in the real world. The virtual avatar is shown to move along the drawn path. For convenience, the avatar moves at different speeds, set in the controls that appear at the bottom of the screen.
