The New York Times reports that researchers in Singapore have invented a device that fits in a window and can reduce loud noises from the outside by 10 decibels. “If you sit in the room, you get that same feeling like when you flick on the switch of noise-canceling earphones,” says Bhan Lam, a researcher at Nanyang Technological University in Singapore that developed the Anti-Noise Control Window.
Their results were published on Thursday in Scientific Reports. The prototype is not yet the most practical device in real world conditions, but it points the way toward the development of technologies that may help ease the strain of noisy city living.
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.
The US Patent and Trademark Office said an AI that invented a food container system and a warning light that flashes in a “hard to ignore rhythm” is ineligible to receive a patent, reports the BBC. The creator of the artificial intelligence system, a researcher name Steven Thaler, said he cannot be considered the inventor […]
“I design Unnecessary Inventions for fun,” says IMGURian @rightcoastguy, who was challenged by fellow users to make this truly silly and wacky invention. “Meet the SockNoMore.”
We all know the game Operation in which the player must conduct surgery on a curious character named Cavity Sam. As the commercial goes, “It takes a very steady hand.” But as sci-tech historian Allison Marsh writes in IEEE Spectrum, Operation evolved from a very different electrified game called Death Valley that was invented in […]
Building blocks are among a child’s first, and arguably, most important, toys. Once they start stacking one tentatively on top of another, the blocks not only spark waves of creativity, but actual real-world understanding of scientific principles like engineering and physics. It wouldn’t even be a stretch to call blocks on of the first true […]
Time management and self-motivation, the ability to stay on task and achieve in the office or when you’re working with home, is the true test of any person’s professional mettle. While that’s easier said than done, those skills can be taught and developed as you’ll find in The 2020 Work From Anywhere Hacker Bundle. The […]
It’s easy to be instantly dismissive about most Bluetooth speakers, especially small travel-sized units. Over the past few years, makers of every shape, size, and variety have started pounding out Bluetooth speakers, many barely able to sound much better than your smartphone speaker, let alone provide the bass and volume heft of legitimate portable speakers […]
