The channel’s latest video demonstrates a gun that shoots a narrow beam of soundwaves, along with its most striking property: ...

Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...

Three physicists from RIKEN have illustrated the ability of an ultrafast form of transmission electron microscopy to quantify sound waves in nanostructures. A cutaway of the ultrafast transmission ...

When I create a wave file that is a sine wave of say, 22KHz, does it actually produce a 22Khz sound? Or do the speakers limit this? Since the average human can only hear 20Khz but when I produce a ...
