To achieve total sound isolation, researchers from the University of Pennsylvania and Lawrence Livermore National Laboratory used ultrasound and nonlinear acoustics to "bend" soundwaves to produce ...

Researchers from the University of Technology Delft, the Netherlands Institute for Neuroscience and Caltech have developed a ...

A bladder ultrasound is a noninvasive imaging technique used to check for abnormalities in the urinary bladder. It involves the use of a handheld device called a transducer that bounces high ...

Crucially, the sound waves — specifically, ultrasound waves — used to create the audible enclaves can't be heard along the path they travel and can even be bent to avoid obstacles. Only when ...

As the technology advances, it gets cheaper, more portable, and more powerful. Since it uses sound waves, an ultrasound doesn’t put the patient at risk for radiation. Despite its usefulness, ...

A bioengineer highlights the potential of low-intensity ultrasound for multiple uses, from enhanced drug delivery to the ...

The principle is the same as the opera singer's trick, where a glass may shatter if the singer makes a high-pitched sound near to the glass. Ultrasound imaging creates a picture of something that ...

Conventional speakers work by moving air around to create sound, but tiny speakers that use ultrasonic frequencies to create pressure and generate sound opens some new doors, especially in terms ...

While medical centres use ultrasound daily, so far this technology is not capable of observing body tissues at the scale of cells. Physicists from the University of Technology Delft (The ...
