The sonic glasses take a video feed right in front of you and turn that into a sonic landscape, so as things move around, and get closer and farther, it sounds like "Bzz, bzz, bzz."
Zvučne naočale snimaju video onoga što je ispred vas i pretvaraju to u zvučni pejzaž, kako se stvari pomjeraju,  postaju bliže i dalje, to zvuči poput "Bzz, bzz, bzz."
