Researchers at the University of Bristol have been able to levitate objects using ultrasonic waves larger than the wavelengths of sound used by the device. This could enable touchless control of drug ...

Ultrasonic toothbrushes could be the key to a novel, highly efficient battery recycling method. New research from the U.K.'s Faraday Institution has suggested ultrasonic delamination could offer a ...

The mating calls of the katydid, a large insect, are ultrasonic, beyond the audible limit of human hearing. What if we could hear them? That’s the focus behind a collaboration between the abstract ...

Ultrasonic gas leak detection methods enable rapid response and improved safety performance in high-risk industrial ...

Apple could use ultrasonic sound waves to deliver haptic feedback to wearers of its upcoming AR/VR headset when they interact with virtual objects. Most consumer AR/VR headsets do not provide haptic ...

Imagine that your smartphone could talk directly to an ATM to securely authenticate your identity without you having to touch it. What if your phone could use sound from the speaker system in the mall ...

Attack uses ultrasonic sound waves to disrupt HHD read/write operations, which could lead to a system crash. Using sonic and ultrasonic soundwaves as a weapon, researchers can disrupt the read, write ...

Humans can observe what and where something happens around them with their hearing, as long as sound frequencies lie between 20 Hz and 20 000 Hz. Researchers have now developed a new audio technique ...

What do bats, dolphins, shrews, and whales have in common? Echolocation! Echolocation is the ability to use sound to navigate. Many animals, and even some humans, are able to use sounds in order to ...
