Goodbye to the noise of the street .. revolutionary windows "sucking the voices"

Scientists have developed a device that can be mounted on windows, absorbing external noise, up to 50 percent, even if it is open.
The prototype, researchers from the Nanyang Technological University in Singapore, have developed a collaboration with experts from Southampton University and Tottori in Japan.
Several devices are combined to form a matrix on window frames, reducing external noise by combining each device with a microphone that detects noise before it reaches the window, creating a sound wave that opposes the incoming ones and cancels them.
The device adopts the "active noise control", which is adopted in speakers that prevent noise, according to the newspaper "Daily Mail" British.
According to the British newspaper, the device was tested at the laboratories of the University of "Nanyang Technological" with sounds such as those of heavy machinery in construction sites, aircraft engines, and trains.
The device is ideal for people living in buildings located on aircraft routes, on busy roads, near markets, or next to annoying neighbors.
