Compared to the much stronger airflow from the box fan that was also used in one attempt, the difference with the sound waves is that they oscillate, constantly fluctuating the air pressure.

The sounds cause the surface of the water to oscillate and create desired wave patterns. A particular sound’s amplitude, phase, and frequency can be adjusted using a laptop computer, so that ...

Sunglasses, for example, reduce glare by blocking out light waves that oscillate in certain directions ... the team found that the intensity of the emitted sound waves changed when the orientation ...

In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave — including halting fat development. “Since sound is non-material, acoustic stimulation ...

Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation ...

These oscillate out of sync with undesirable sound waves and therefore cancel them out. The same principle is at play in noise-canceling headphones, which work well in tiny spaces, such as ears ...
