Researchers in China recently uncovered a quantum-inspired rule governing how sound is scattered by certain physical ...

Transmitting information between underwater and airborne systems has long posed a technical challenge. Sound behaves very ...

A porpoise’s forehead acts like a ‘metamaterial’ to create the directional sound beam used by the marine mammals to detect and track prey, claim researchers in the US and China. The acoustics experts ...

In our increasingly noisy world, it can be hard to find some quiet time. Now, a team of mechanical engineers at Boston University has developed a new device that is specially designed to block up to ...

Boston University researchers, Xin Zhang, a professor at the College of Engineering, and Reza Ghaffarivardavagh, a Ph.D. student in the Department of Mechanical Engineering, released a paper in ...

Synthetic, sound-silencing structures—acoustic metamaterials can block 94% of sounds. This ring of materials will be able to make vacuum cleaners, air conditioners, fans and other devices and products ...

Blocking sounds and creating silence even within a noisy environment is possible with the help of acoustic metamaterials. Researchers at Boston University discovered that they can harness their ...

The control of acoustic applications such as loudspeaker design, ultrasound imaging and acoustic particle manipulation currently relies on using fixed lenses and expensive phased arrays. Now, a team ...
