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 ...

Researchers have come up with a new and improved way to levitate objects using sound waves alone, an impressive feat of mixed-reality technology that could pave the way for some seriously futuristic ...

Researchers have found a way to make materials that are normally opaque to sound waves completely transparent. Their system involves placing acoustic relays at strategic locations so that sound waves ...

A boiling tea kettle diffuses its heat to gradually warm surrounding air, yet it will still be the warmest region even as it, too, slowly cools. But what if the kettle cooled down to room temperature ...

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...

Phononic crystals are novel materials that offer exceptional control over phonons, sound and other mechanical waves. Taras Gorishnyy, Martin Maldovan, Chaitanya Ullal and Edwin Thomas report on a ...

Hey all! So all my life I have heard that sound is a type of wave. This seemed to make sense to me. Recently I have come across some information that has me second guessing such tradition knowledge.

At the start of my career, I used to do acoustic testing in an anechoic chamber where sound is not reflected as it gets absorbed. But the quietness of these chambers always got me thinking of how ...
