To provide a fiber aggregate for sound insulation that is able to effectively insulate sound by a simple structure, a sound absorbing/insulating material and a sound absorbing/insulating material fora vehicle that comprise this fiber aggregate for sound insulation. This fiber aggregate for sound insulation has a mean fiber diameter of 450-8500 nm and a bulk density of 0.09-0.33 g/cm3. It is particularly desirable that the fiber aggregate for sound insulation have a mean fiber diameter of 450-1650 nm and a bulk density of 0.09-0.22 g/cm<3>. The fiber aggregate for sound insulation is lightweight and can effectively provide sound insulation performance by satisfying these numeric ranges.

    提供一种能够以简易的构造来有效地隔音的隔音用纤维聚集体、具有该隔音用纤维聚集体的吸音隔音材料以及车辆用吸音隔音材料。隔音用纤维聚集体的平均纤维直径为450nm~8500nm,堆积密度为0.09g/cm~0.33g/cm。尤其优选隔音用纤维聚集体的平均纤维直径为450nm~1650nm,堆积密度为0.09g/cm~0.22g/cm。隔音用纤维聚集体通过满足这些数值范围,能够实现轻量化并有效地发挥隔音性能。
