Engineers at Switzerland’s École Polytechnique Fédérale de Lausanne (EPFL) have created a system that harnesses audible sound waves to steer objects across an unpredictable aquatic obstacle course. But as neat as it is to watch speakers maneuver a floating ping-pong around a pool, the process known as “wave momentum shaping” may also pave the way […]
Arachnids are born dancers. After millions of years of evolution, many species rely on fancy footwork to communicate everything from courtship rituals, to territorial disputes, to hunting strategies. Researchers usually observe these movements in lab settings using what are known as laser vibrometers. After aiming the tool’s light beam at a target, the vibrometer measures […]
Researchers at MIT have designed a new underwater communication system that employs 70-year-old technology while also requiring one-millionth the energy needed for existing arrays. Not only that, but the team’s design allows for transmissions that can travel 15 times farther than current devices. “What started as a very exciting intellectual idea a few years ago—underwater communication […]
A passive phone amplifier will make your phone audio louder, but some look like trash. Build this wooden one so your setup both sounds and looks good.
Sir Paul McCartney explained to the BBC that an AI-driven process helped isolate John’s vocals from an old tape for a last Beatles album.
Reflected sounds help bats, dolphins, and other animals navigate in extreme darkness—and humans can even train themselves to learn echolocation.
How did the Apple Mac computer develop its signature startup chime? The composer behind it shares the story.
Music can take us to places past and present, whether it be middle-school heartbreak or reliving your teenage dream. The Bowers & Wilkins Zeppelin speaker can help elevate your tunes for a light vibe, thanks partly to being $200 off on Amazon. Typically $799 but temporarily available for $599, its lowest price in months, the […]
The system can both use sound to try to visualize what an unseen space would look like, or simulate sound in virtual reality.
There are plenty of songs about the month of September that you can stream through your speakers: Green Day’s “Wake Me Up When September Ends,” “September Gurls” by Big Star, and the GOAT “September” by Earth, Wind & Fire, to name a few. And all of them sound even better with a subwoofer from British […]
