The background sounds of urban environments can be invigorating when you are out and about, but enervating when you are at home and want to tune them out. Now imagine a simple gadget you can stick to your window letting you do just that – a volume knob for everyday life.

Sono is a remarkable working prototype, created and tested by industrial designer Rudolf Stefanich that “turns your window into an advanced noise cancelling system that allows you to eliminate and/or control the sounds that pass through.”

Cancellation of background noise is just the first step, however, with specific-sound filtering and replacement via a user-friendly touch interface as advanced options.

The gagdet will allow to you dial up or turn down the sounds of car sirens, traffic horns and other intrusive distractions, but it will also give you the power to select a preferred ambient audio experience instead. It effectively offers an adjustable soundtrack of your own choosing.

From its creator: “In our loud and busy world a moment of silence has become a scarce and almost luxurious experience. The pebble like device you can see here lets you reclaim that silence for your home. With its concentric broadband antenna rings, it harvests the energy of electromagnetic noise from Wi-Fi, and similar signals and this way also reduces the level of e-smog pollution in your environment.”
