Rainbows of sound are a reality thanks to a new device

Scientists have created an acoustic rainbow using a small plastic device that separates white noise into different pitches. The oddly shaped structure, inspired by the human ear, directs sound frequencies from 8 to 13 kilohertz to distinct locations around it. Researchers used inverse design and 3D printing to create the device, which could have practical applications in manipulating room acoustics. The acoustic rainbow demonstrates a novel way to manipulate sound, offering potential for future acoustic technologies.
