Уникальные оконные технологииЮжнокорейские ученые придумали, как отделить звуковые волны от воздуха, в котором они распространяются, сообщает Voz de Galicia в статье, подготовленной агентством Europa Press. Изобретатели говорят, что для этого используется "относительно простая" конструкция.

Ученые из Морского университета Моклхо и Корейского института машиностроения и материалов сконструировали окно, которое "дышит", но не пропускает звуки. В публикации на arxiv.org эксперты заявили, что это окно спасет от "акустического загрязнения" - то есть от излишнего шума.

Собственно, речь идет о камере из прозрачного акрила, которая, по словам авторов исследования, имеет "отрицательный коэффициент сжимаемости": "любой звук, который резонирует в камере, противодействует любому звуку, который ее сжимает, что обеспечивает отрицательный коэффициент сжимаемости". В акриловых пластинах просверлены отверстия, которые служат для дифракции звуков, а заодно для вентиляции. Если верить изобретателям, можно так рассчитать диаметр отверстий, чтобы заглушались лишь нежелательные звуки: например, вы будете слышать прибой, но не шум оборудования.
