Abstract

Изобретение относитс  к области машиностроени  и предназначено дл  изготовлени  звукоизолирующих покрытий шумозащитных конструкций. Целью изобретени   вл етс  увеличение звукоизолирующей способности в услови х повышенной влажности. На поверхности волокна 1 из гидрофобного звукоизолирующего материала выполнены поперечные кольцевые канавки 3, заполненные гидрофильным звукопоглощающим материалом. Внутри волокна 1 вдоль его оси между канавками 3 размещены вакуумированные полости 2, непроницаемые дл  звука. 3 ил.The invention relates to the field of mechanical engineering and is intended for the manufacture of soundproofing coatings for noise protection structures. The aim of the invention is to increase the sound insulating ability under conditions of high humidity. On the surface of the fiber 1 of the hydrophobic soundproofing material made transverse annular grooves 3, filled with hydrophilic sound-absorbing material. Inside the fiber 1, along its axis between the grooves 3, there are evacuated cavities 2, impervious to sound. 3 il.
