Mathematicians and engineers at the University of Utah have teamed up to show how ultrasound waves can organize carbon particles in water into a sort of pattern that never repeats. The results, they ...

ANC does not shut the world out. It listens to outside noise, flips the sound pattern, and makes certain sounds feel weaker ...

Patterned elastic plate guides ultrasonic waves and traps different frequencies at separate bulk locations, enabling compact ...

The top layer represents the location of the sound source and the path of sound propagation (A). The bottom layers represent convergence zones with different sound propagation paths (B-F). Sound waves ...
