People love New York City partially because it’s the city that never sleeps. But a city active 24 hours a day also means it’s producing noise 24 hours a day, making it for many the city that can’t sleep. Traffic, construction, loud guys playing dominoes. Sometimes, silence in the city is like a permanent parking spot: a luxury that most city dwellers can only dream of. Sono, created by Rudolf Stefanich, is looking to give people some peace and quiet. The circular device attaches to a window to get rid of the unwelcome noises outside the apartment. However, city people may have to wait a long time before it hits stores, as it’s still only a prototype product as this stage. According to Stefanich’s description of Sono, the product acts like a set of noise-cancelling headphones. The device comes with a microphone that detects and analyzes the noise outside the window. It then plays back that noise, but out of phase.
