The system uses a microphone outside the window to detect the repeating sound waves of the offending noise source, which is registered by a computer controller. That in turn deciphers the proper wave frequency needed to neutralize the sound, which is transmitted to the array of speakers on the inside of the window frame. — The New York Times
A team of researchers at Nanyang Technological University in Singapore led by Masaharu Nishimura and Bhan Lam have developed a prototype approach that can decrease the amount of urban noise that infiltrates a dwelling.
The grid of circular speakers is installed within the open window frame and filters out constant sounds of a certain frequency. It has yet to be perfected to block out sporadic and low-pitched sounds, however.

This is the issue that bothers me. When you get those boomin' cars and other music with da BASS it's nearly impossible to stop the low frequencies' long wavelengths. And that rumble and noise of everything filtered out except the bass really bugs me. I feel it in my bones, (hu)man!
But it's exciting progress on this issue! Good to hear (or NOT hear) here, here!
I actually liked sleeping to the white noise of NYC when living there, even made a recording of it to use elsewhere.
white noise? that's racist!
JUST KIDDING
i do like the white noise in an urban environment. and i used to live in a crappy apartment on the wrong side of the train tracks and found the trains in the middle of the night quite soothing.
where was this 20 years ago?...I hate reggaeton due to crappy windows now...same damn base line, every song, every song sounds like Gasolina...
This is awesome and could expand on install uses, to doors, hallways, etc...just cancel it all out.
have it installed in clothes or walk around with a giant boombox cancelling out all the noise wherever you go.
