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 ...

For many nocturnal moths, hearing sound waves is a matter of survival in the night sky. Their ability to detect ultrasonic ...

Engineers at the Massachusetts Institute of Technology (MIT) have developed an ultrasonic device that dramatically ...

In the new device, an array of 256 speakers, each about 1 centimeter wide, faces another, identical speaker array across a distance of 23 centimeters. The speakers emit sound waves at frequencies too ...

Curtin University researchers have developed a new technique to make glass water-repellent, a feature that could improve safety in vehicles, reduce cleaning costs for buildings and enhance filtration ...

Engineers at Duke University have developed a wireless patch that can noninvasively measure skin and tissue stiffness at depths of up to a couple of inches. Already smaller than a smartwatch, the ...

MIT researchers have found a way to use the mechanical vibrations of sound waves to shake water molecules free from a storage ...

Washington University Researchers have discovered that voice assistant programs like Siri can be hacked with ultrasonic sound waves that go undetected by human ears - but you probably won't have to ...

We can hear sounds because our ears turn sound vibrations from the air, into signals that are sent to our brain. We can’t hear all levels of sounds. Sound waves with very high frequencies are called ...
