Abstract

Изобретение касается слоистого звукопоглощающего нетканого материала, содержащего резонансную мембрану и по меньшей мере один следующий слой (1, 3) волоконного материала. Резонансная мембрана звукопоглощающего материала образована слоем (2) нановолокон диаметром до 600 нанометров, поверхностной плотностью 0,1-5 г/м, при этом резонансная мембрана формуется вместе со следующим по меньшей мере одним слоем (1, 3) волоконного материала путём поперечного накладывания до получения нужной толщины и необходимой поверхностной плотности.
