A shotgun is obviously the more satisfying approach, but researchers at the Korea Advanced Institute of Science and Technology have found a simpler way to knock drones out of the sky—by targeting their onboard gyroscopes with nothing but sound.
When it comes to undesired noises, silencing guns is the same thing as silencing incessant yammerers. It all comes down to dealing with hot gas.
If you picture what sound looks like in your head, you'll probably think of some picture graph of a sound wave. But no one can actually see those up and down scribbles with their eyeballs. So what does sound actually look like in real life? It's invisible but sound looks like what you see in the GIF above. A gust of…
What is the texture of the universe? Turns out that it's kind of gooey. A group of physicists have used sound waves to analyze matter in the cosmos, and found that its consistency is exactly the same as chocolate syrup.
Go to this website, pick a material, send in an audio file. Get back jewelry in shape of the sound wave you gave them. It's simple, and oddly beautiful.
Imagine Lex Luthor as a really nice guy and you'll be pretty close to understanding Alfred Loomis. He was a scientist and inventor, a businessman and investor, a wealthy and prominent man. And he also invented the "Death Ray."
Got some free time and some candles? Try to extinguish a flame with your voice! We know it can be done, we're just not sure how it can be done. Maybe you'll have a breakthrough. Or maybe you'll just have a housefire.
As the only metal that is liquid at room temperature, mercury is freaky even under normal conditions. But check out what happens to a blob of the stuff when it's exposed to a different audio frequencies.
This may look like a magic trick, but YouTube user Brusspup is just using the science of sound waves and camera frame rates to make this stream of water dance.
It looks like the kind of spit you'd roast a pig on for some sort of tropical luau cookout. Except instead of flames, there is a supersensitive laser rangefinder. And rather than a suckling pig sizzling, there is a clown head seemingly singing. Or a roll of paper towels.
You might think the trippy animated visualizations in your media player are the best way to see your music. But astronaut Don Pettit has found a better way—and all it requires is a small set of speakers, a blob of water, and a space station 250 miles above the Earth.
Japanese electronics company Kyocera has developed an innovative new transducer to replace outmoded—and underperforming—speakers in a phone.
How do you make an underwater invisibility cloak? You start by creating a device that can manipulate sonar waves. This small cylinder, developed by researchers at the University of Illinois, does just that.
Neurologists have built an ultrasound device which uses focused sound waves to destroy stroke-causing blood clots in brains. The procedure is non-invasive—requiring no drugs or surgery—and is already being tested on patients.
This concept of a sewing machine was created by SOUNDS.BUTTER, a design group interested in physically representing sound waves. They sought to represent it tactically instead of digitally where sound is oft seen in sound and music editing. The sewing machine was chosen because of its association with industriousness…
Scientists at Rensselaer Polytechnic Institute have come up with this freaky adaptive liquid-lens that can capture 250 in-focus images per second. It's essentially droplets of water in a pair, trapped in chamber and driven by a high-frequency sound wave to oscillate.As the drops wiggle back and forth, surface tension…
