In a makeshift demonstration kitchen in Concord, California, cooking oil splatters in and around a frying pan, which catches ...

NASA wants to make supersonic travel quieter. On Thursday the agency released new footage of its X-59 jet, a ...

High-frequency ultrasound platform for preclinical imaging, supporting real-time visualization of small animal anatomy and ...

Infrasound waves are usually too low for the human ear to actually hear, but they can still have a negative effect on ...

A new device for creating individual "phonons" — vibrational quanta — could give rise to the acoustic equivalent of lasers.

Doppler ultrasound works by measuring frequency shifts in sound waves as they bounce off moving red blood cells, translating them into waveforms that reflect blood flow patterns. In obstetrics, this ...

Doppler ultrasound blends physics and medical imaging to reveal the movement of blood through vessels and the heart. From diagnosing clots to assessing heart valve function, it’s a non-invasive tool ...

Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...

Several counties across the Chicago area were under severe thunderstorm watches and warnings as a morning line made its way through -- and more is on the way. A ground stop was issued for flights ...

Physicists at New York University in the US have built a new kind of time crystal using sound waves, where particles appear to break Newton’s famous third law of motion. Particles in this time crystal ...

A team of researchers co-led by the University of California San Diego, University of Michigan, and the French National Center for Scientific Research (CNRS) at Laboratory of Acoustics of Le Mans ...

Abstract: Wing flapping of insects can cause micro-Doppler patterns in the reflected signals. Here we study the feasibility of insect sensing from a joint waveform from a near-field continuous-wave ...
