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 ...

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 ...

Researchers have developed three designs for compact speaker systems that control the direction of sound more efficiently than previous models. For each speaker, the scientists were able to manipulate ...

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 ...
