Sound has a speed limit. Under normal circumstances, its waves can travel no faster than about 36 kilometers per second, physicists propose October 9 in Science Advances. Sound zips along at different ...

To the recording studio to study interference and diffraction of sound waves. Unit 6 Segment D: Sound: Diffraction and Interference We head back to the recording studio to study interference and ...

Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that ...

In order to understand the macro dynamics of materials, scientists need to understand what instigates certain phenomena, which occur on infinitesimally small timescales. To this end, scientists at the ...

Ascending scale: sound waves rise as they travel through media. (Courtesy: Shutterstock/Appler) A new theoretical study has revealed how sound waves transfer small amounts of mass as they travel.

Yale scientists used laser light to gain access to long-lived sound waves in crystalline solids as the basis for information storage. The result was published online April 2 in the journal Nature ...

Yushun Zeng squishes cancer cells in a petri dish at work. No, not with his ungainly, macroscopic human fingers. Zeng, an engineering graduate student at the University of Southern California, has ...

Students learn how sound waves are produced and transmitted. Students learn how sound waves are produced and transmitted and how frequency is related to pitch. The speeds of sound in different media ...
