The use of ultrasonic noise — silent to the human ear — in mobile payments and rewards hasn't garnered as much attention as Near Field Communication chips and QR codes, but there are a few successful ...

Are you looking to work smarter instead of harder when it comes to your usual house cleaning routine? Different technologies and methods promise better results for less effort but some are gimmicks.

Noise and vibration are very effective activators of stress pathways in rodent models that can increase variability in animal models, thereby confounding virtually every area of biomedical and ...

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 ...

An ultrasonic range finder is a useful tool in a variety of real-life and robotic applications, such as in obstacle-avoidance and distance-measurement systems. The ultrasonic range finder measures the ...

A unique ultrasonic bracelet has been created which is capable of jamming microphones in smart speakers when in close proximity. The wearable microphone jammer has been designed to exploit a synergy ...

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 ...

Smart speakers and other microphone-equipped devices aren't supposed to listen all the time, but there might be a solution if you aren't willing to take any chances. University of Chicago researchers ...

When tiger beetles hear a bat nearby, they respond by creating a high-pitched, ultrasonic noise, and for the past 30 years, no one has known why. In a new study, scientists lay the mystery to rest by ...
