The Light and Sound Quiz Show

The science of light manipulation started with the ancient Greeks, so we have had many years to develop it. Lenses and holograms are part of our everyday lives. Light and sound are very similar: they are both waves, and they both have particles associated with them. So, why do we not have lenses or displays for sound? Or do we? This article will tell the story of how sound technology is catching up with light technology. We will tell you about acoustic metamaterials, an emerging technology that is quickly becoming part of our loudspeakers, our shows, our cars, our public spaces, and our hospitals—all the places where we want control over sound and noise. The future of shaping and designing sound is in the making! Maybe someday, sound experts will even teach something to light experts!
