The development of acoustic metamaterials has brought with it a strong drive towards bringing electromagnetic concepts to acoustics. Thus, the extended range of material parameters provided by ...

Explore how metamaterials are revolutionizing architecture with acoustic invisibility, earthquake resilience, and energy ...

Acoustic and mechanical metamaterials can route and control sound with an unprecedented degree of control. We expect many more wonders, ...

So-called "acoustic metamaterials" are specifically designed to control and manipulate sound waves, usually for the purpose of dampening or transmitting sound. But such an acoustic device can only ...

In other words, the acoustic metamaterial needs to be immersed in something dense, like water, before it will function. As noted above, however, acoustic metamaterials that function in air would ...

New 'acoustic metamaterial' cancels sound Mechanical engineers create synthetic, sound-silencing structure that blocks 94 percent of sounds Date: ...

A metamaterial with acoustic properties that can be reconfigured in less than one tenth of a second has been made by researchers at the University of Bristol in the UK. Created by Mihai Caleap and ...

This presents an opportunity to 3D-print small acoustic systems that can be stacked together to create acoustic metamaterials that work at audio frequencies. “Unfortunately, acoustic metamaterials, ...

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 ...

Acoustic Metamaterials Group uses recycled plastic to manufacture noise-cancelling barriers for the construction industry; Start-up’s founder received US$435,000 from the Hong Kong government ...
