In the worst case, these vibrations can destroy the engine. Noiray had the idea to use harmless self-sustaining aero-acoustic ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

Why is this ? If sound is caused by vibrations, why do the waves of the atmosphere produced in these instances not cause sound ? It has been demonstrated by accurate experiments that the air must ...

A team of researchers has for the first time successfully used lasers to generate guided sound waves on the surface of a microchip. These acoustic waves, akin to the surface waves produced during an ...

Certified Sound Healer and Mental Health Coach Nicole Smart recently joined Bloom host Gayle Guyardo to share insights on the ...

Europe is preparing for climate-neutral flight powered by sustainably produced hydrogen. Last year, the EU launched a project ...

These acoustic waves, akin to the surface waves produced ... As light moves around the chip or an optical fibre, it creates sound vibrations. Previously seen as a nuisance in optical communication ...

Here's how it works. First, vibrations in the ground are created using airborne sound or seismic wave vibration excitation ...

capturing sound through vibrations in the air. When someone speaks, sound waves hit the eardrums, vibrating and sending signals to the brain. But unlike the clarity the eyes offer, ears can ...

MIT researchers have created acoustic silk that could become cubicle or thin wall panelsthat reduce sound in large spaces.

One problem is vibrations, which engineers try to minimise. In typical jet engines, about twenty fuel injection nozzles are arranged around the annular combustion chamber of the engine. The turbulent ...
