Scientists Say You Can Cancel the Noise but Keep Your Window Open

Researchers in Singapore developed a system that’s sort of like noise-canceling headphones for your whole apartment according to the NY Times.

Sure, closing the window can help, but there goes your natural ventilation.

What if there were technology to cancel the offending clamor, like a pair of giant noise-canceling headphones for your apartment?

Researchers in Singapore have developed an apparatus that can be placed in a window to reduce incoming sound by 10 decibels.

“I grew up in Singapore,” Dr. Lam said in a Zoom interview from his apartment there. “It’s a small city with a lot of noise, so I have some motivation to solve this problem.”

Borrowing from the same technological principles used in noise-canceling headphones, the team expanded the concept to fit an entire room by placing 24 small speakers in a window. The speakers emit sound waves that correspond to the incoming racket and neutralize it — or, at least some of it.
