Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has ...
A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.
Sound waves travel through different types of matter, including liquid water. Importantly, the movement of ocean water can greatly affect how sound waves travel from one point to another. Mesoscale ...

The clue to the answer is in the second part of the question, which mentions “various frequencies”. In 1822, French mathematician and philosopher Joseph Fourier effectively proved that every sound can ...
Forget fad diets and sketchy supplements, your favorite song might be the key to staying thin. In a new study, Japanese researchers found that acoustic sound waves can influence how our cells behave — ...
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 ...
