Sick of city din? Singapore scientists devise 'noise-cancelling headphones' system for your flat

Scientists believe they have found a way for city dwellers to let in fresh air while reducing the urban cacophony -- and it is a bit like popping massive, noise-cancelling headphones onto your flat.

When noise such as traffic or a subway train is detected, the speakers generate sound waves that cancel out some of the din -- much in the same way some high tech headphones work. While blocking the racket from outside, it also"lets in the natural ventilation and lighting through the windows," he told AFP, at a lab where a prototype of the device had been set up.
