Revolutionary Device Enables One-Way Sound Transmission

Researchers at ETH Zurich have developed a groundbreaking device that enables sound waves to travel in a singular direction, enhancing communication technologies. This innovative disk-shaped cavity uses swirling air to manipulate sound waves, allowing for non-reciprocal transmission, which can improve noise suppression and sound isolation. With potential applications in telecommunications and audio engineering, this advancement could revolutionize how we interact with sound.
