Researchers in Singapore have invented a way to help urban residents find peace and quiet.
The system functions similar to noise cancelling headphones.
When 24 small speakers are placed on the metal grill, it creates an acoustic shield over an open window.
When noise is detected, the speakers transmit a sound to deaden part of the noise.
The system still allows light and fresh air to pass though the window.
It reduces noise levels by up to 10 decibels.

He explains that we can't block out sound completely.
The World Health Organisation has identified many health concerns worsened by noise.
