Tests are ongoing at Virginia agricultural fields and airports, with plans to test the net on large urban structures, such as cell towers and skyscrapers, to help prevent bird strikes. The researchers are also exploring how their sonic net can reduce crop loss in sub-Saharan Africa.
Hinders likens the device’s effect to being at a cocktail party. “You’re in a room where a lot of other people are talking. It can be difficult to follow an individual conversation,” he says. “It doesn’t even have to be especially loud. We fill in the gaps in their conversations with noise.”
And by crashing the party, the sonic net could save the birds and our crops.
