  • Steve Cummer, professor of electrical and computer engineering at Duke University, explains the various projects he is working on to use metamaterials to manipulate sound waves.
    Duke-developed “metamaterials” are carefully designed structures that control all sorts of energy waves in previously impossible ways. Our researchers are poised to make these devices a household name.

    Interesting to see this now and having been looking at the KEF LS50 M ( for meta!) loudspeakers, which are using meta material discs to absorb back reflections from the drive units.

    How about metamaterials to improve aerodynamic efficiency and stability, without compromising on other properties like lift/downforce, maneuverability, etc?

    Where can I find more information on its applicability for ultrasound?

    1:25 "which has the effect of slowing down sound waves that pass through that structure"
    Is this considered a way of accomplishing an acoustic black hole?

    Can this be used to create a two way sound 'mirror', reflects on one side, transmits on the other?

    Please make a room that blocks city and road noise, but allows the sound of wind in the trees, birds, and nature through.

    Maybe the aliens that live at the bottom of the ocean are using meta materials to make their structures undetectable

    Noise control of a single frequency?
    Helmholtz, and quarter wave resonator do exactly that....

      As he mentioned, metamaterials are much more compact. Also, 3D printing would allow much better quality control over home-made designs typically employed in home theater applications.

      @@bobsondugnutt7526 how do you logically separate “home made” and “3D printing” these days? Even metal sintering machines are becoming available and for acoustics PLA is plenty.

    And here I was, thinking orchestras have beautifully sounding instruments, which sadly get their specialty drowned out by usually massive amounts of distracting reverb.
    The proposition, at least one of them, is to bring diffuse sound home?
    Sounds like a suboptimal pitch.

    Really interesting but he could've done a better job explaining in layman's terms by using simpler real world examples. I barely understood the ultrasound example, despite all of his techno speak.
