New technology (HDSP) developed by Mohsen Habibi from UC Davis uses 3D printing with soundwaves to repair broken bones.

Ultrasonic sounds are high-frequency sound waves that exceed 20,000 hertz, a range far beyond what the human ear can detect.

For the first time, MIT scientists have successfully imaged how heat actually travels in a wave, known as a “second sound,” through this exotic fluid. Understanding this dynamic could help ...

Air vibrates back and forth within the neck, creating sound waves of a frequency that depends on the volume of the cavity and the dimensions of the neck and opening. When a person claps their ...

To capture the imagery, NASA used ground telescopes with special filters that detect air distortions, such as shock waves, around the supersonic aircraft. On Jan. 28, the aircraft broke the sound ...

A newly released image shows the sound barrier being broken on February ... ground used Schlieren photography to capture the shock waves around Boom Supersonic’s demonstrator aircraft XB-1 ...

"The sound waves create microscopic bubbles in a diazonium salt solution, which then collapse rapidly, creating tiny bursts of heat and pressure," Associate Professor Darwish said. "This triggers ...
