Acoustic Metasurface Enhances Underwater Sound Transmitted to Air

■ Natural Sciences / Acoustic Metasurface Enhances Underwater Sound Transmitted to Air A newly developed ultrathin acoustic metasurface can greatly enhance the levels of underwater sound transmitted to air, allowing new forms of underwater sonic sensing and communication to be developed. Have you ever stood on the bank of a river and wondered why you cannot hear fish or plants moving beneath the surface? After all, sound travels well in water. The explanation for this silence is that only a tiny fraction of sound (0.1%) traveling in water can cross the barrier between water and air. In a study recently published in the scientific journal … Continue reading Acoustic Metasurface Enhances Underwater Sound Transmitted to AirRead More →
