According to the Smithsonian, two Korean researchers, Sang-Hoon Kim and Seong-Hyun Lee, have developed a window that is able to block sounds but still let air in.
The trick, says MITs Technology Review, comes from a clever design strategy that let the window effectively damp the sound out of the air before it passes through.
To make their soundproof window, the scientists took two sheets of plastic and drilled tiny little holes in them. As the air passes through the holes the sound waves get diffracted.
But if this was all they did, say the researchers, your windows would sing like a wind instrument. So from here, once the sound waves are diffracted, they bounce around in a little chamber, sandwiched between the two pieces of plastic. Inside these little chambers, they say, the sound waves are attenuated. By hooking a few of these little chambers up in a row, each with a different sized hole to let the air through, the windows can strip different frequency bands of the sound from the air.
