Absorbing excess sound to make public environments like theaters and concert halls safer for hearing and using the unwanted sound waves to create electricity is the aim of a new paper. The authors ...

This array of piezoelectric sensors is designed to install in theaters and concert halls to harness sound wave energy to create electricity. This miniature proof of concept included 1,042 sensors, and ...

Physicists at New York University have built a time crystal powered entirely by sound waves, and lab tests suggest the ...

A team co-led by UC San Diego and the University of Michigan reports that short pulses of sound could remotely drag a structural defect through a metamaterial lattice, potentially letting researchers ...

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 ...
