Woven spacer fabrics filled with foam had better strength and acoustic insulation property, and the biggest sound attenuation of the spacer fabric with 4 mm space height achieved 26 dB.
织造密度大的普通单层机织物隔音性能好,具有一定厚度的多层机织物要考虑其体密度,即厚度及表面密度都大的隔声性能好,填充泡沫后的间隔机织复合材料,其强力及隔声性能均较优,其中间隔高度4mm的机织间隔织物最大的声级衰减量达到了26dB。
