A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

Researchers from IMDEA Materials Institute, in collaboration with China's Nanjing and Huazhong Universities, have developed a ...

Researchers have taken a novel approach to studying the interaction between certain topological metamaterials and sound wave propagation. The technique, described by IMDEA Materials' Dr. Johan ...

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 ...

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

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 ...
