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 ...

In a breakthrough experiment, physicist and engineers have shown that it is possible to limit the movement of sound to a single direction without interruption even when there are deformations along ...
