Blaring a playlist of Metallica tracks hand-picked by the band results in "low-hertz sound waves so intense that it actually enhances the molecular interaction" of the whiskey and alters its ...

Researchers at ETH Zurich have managed to make sound waves travel only in one direction. In the future, this method could also be used in technical applications with electromagnetic waves.

In our everyday world, waves are stubbornly democratic. Whether it’s the sound of a conversation, the glow of a lightbulb, or the undulations of the ocean, waves tend to flow equally in both ...

Ultrasound waves have a frequency above 20 000 Hz, other than that they are like sound waves in every other way. Figure caption, The normal range of human hearing (20 Hz ...

Audible sound can affect gene activity in mouse cells, boosting the attachment of muscle precursors to surrounding tissue and decreasing fat accumulation ...

Sound travels in the form of wave. ... For example: if 10 complete waves or vibrations are produced in one second then the frequency of the waves will be 10 hertz or 10 cycles per second.

As a sound wave hits the meta-mirror, ... In the proof-of-concept demonstration, the metamaterial device takes a soundwave traveling directly toward it at 3,000 Hertz, ...

Researchers with Microsoft and the University of Washington in Seattle have created a program that lets people turn almost any computer, including laptops, into a gesture-controlled machine.

Key concepts Physics Sound wave Frequency Pitch Hertz. Introduction Can you name the bestselling musical instrument in the world? If you said…harmonica, you're right! The harmonica was patented ...

If you wanted to deaden a 20-Hz sound wave using conventional noise reduction foams or sound-absorbing walls, you'd need to have something about 4 m (13 ft) thick.

As sound waves propagate through water, ... Rice adds, however, that the underwater noise from real wind turbines is far more complex than the lone 100-Hz sound tested in the study.
