EPFL researchers have developed a 100% effective, ultra-thin active noise cancelling system that uses an ionized air plasma propulsion system instead of speakers. A 17-mm-thick (0.6-in) layer can block 20 Hz noise as well as a 4-m-thick (13-ft) wall.Co… Continue reading Plasma-based noise cancelling could silence rooms, cars and planes
Many students of guitar begin their journey on an acoustic. But rocking out can be a challenge. Back in 2017, France’s HyVibe launched an Indiegogo to fund a hybrid with built-in digital smarts. This was followed by a kit to give such superpowers to an… Continue reading Self-install Essential kit turns any ol’ acoustic into a smart guitar
Whisper Aero says its electric aircraft propulsion systems are “20% more efficient and 100x quieter than anything else on the market.” They’re designed for drones, planes and possibly eVTOLs, and there’s also a funky-looking concept plane.Continue Read… Continue reading Whisper Aero claims radical advance in quiet, efficient electric jets
Researchers have taken another step forward in medical micro-robotics, designing a tiny, speedy, self-propelled bot that may one day deliver medications directly where they’re needed inside the body.Continue ReadingCategory: Robotics, TechnologyTags: M… Continue reading Sound-powered microbots zip to where they’re needed to deliver drugs
Using touchscreens or pushbuttons to control devices isn’t always practical, and voice commands may not work in loud environments. A new system offers an alternative, in that it utilizes acoustic waves which travel across the surface of existing object… Continue reading SAWSense tech turns almost any surface into a tactile interface
A new 16-string, single-fret acoustic instrument called the Hanago has launched on Kickstarter, which is designed to combine the best aspects of piano and guitar to make learning to play easy, while also laying down the foundations of music theory.Cont… Continue reading Single-fret Hanago makes a play for future tunesmiths
While there are some mechanical problems that can easily be detected by a car’s onboard sensors, there are others which are a bit trickier. The V2M system is designed to catch those other ones, by listening for them using onboard modules.Continue Readi… Continue reading V2M tech is designed to catch car problems – by listening for them
Scientists have created “acoustic holograms” that can assemble matter into 3D objects, using just sound. The technique works with various types of particles and even living cells, allowing for a new kind of 3D printing that’s fast and contact-free.Cont… Continue reading “Acoustic holograms” quickly assemble objects from particles or cells
Engineers at the University of Minnesota have developed a new system that can move objects without making physical contact. The technique involves ultrasound waves acting on specialized surfaces to push or even pull objects in different directions, whi… Continue reading Ultrasound metasurfaces move large objects without touching them
While seabed-located cameras are great for tasks such as monitoring wildlife, powering them and retrieving their photos can be challenging. That’s where a new MIT-designed camera comes in, as it requires no battery, plus it wirelessly transmits its pho… Continue reading Battery-free MIT underwater camera is powered by sound
