Sono, a prototype noise-cancelling device, filters out the annoying sounds of a big city while still allowing the pleasant noises of nature to come into your home. Sound preferences can be adjusted using the scroll panel located on the device.

Living in a metropolis has plenty of perks: convenient metro systems, plenty of gourmet dining choices and endless shopping destinations. But with all that activity comes a whole lot of noise pollution, a nearly unavoidable side effect of living with millions of other people. That noise is likely to permeate your overpriced apartment via your windows, unless you’ve gone through the trouble of retrofitting it with the soundproof kind, which is yet another inconvenient headache.
