Noise cancelling headphones are nothing new, but wouldn’t it be neat if there was a device that could provide an entire room with silence? You could soundproof your room, but that would be time-consuming and expensive. Rudolf Stefanich’s Sono concept device would be a godsend. You’d simply attach it to a window and it would block outside noise.
Aside from cutting down on background noise, Stefanich dreamt up Sono to also be able to let certain sounds pass through, perhaps depending on their noise level. He also imagines that the device will get its power from nearby Wi-Fi signals.
You can find out more about Rudolf’s unique concept on his website. I don’t know if it’s possible to make the Sono a real thing, but dammit if folks are already printing pizza and controlling drones with their minds maybe a reverse cone of silence isn’t too much to ask for.
