• A Quiet Place: ITMO Physicists Reduce Noise Tenfold With Metamaterial Structure

  Imagine you are in a park in the bustling downtown and there is sunshine, fresh air, and… total quiet. Doesn’t feel real, does it? Researchers from ITMO University have developed a translucent vented structure that decreases noise by up to 20 dB within the spectral range of 2 to 16.5 kHz. This means that it covers 70% of the audible bandwidth. The new structure can be used to build noise-insulating barriers alongside roads or pavilions in parks.
