The resonant characteristics is calculated and analyzed in different backings.
并对不同背衬下的情况进行了计算并分析了谐振特性。
The results show that the influences of various backings on the acoustic characteristics of anechoic coating are obviously different.
结果表明，不同背衬对吸声覆盖层吸声性能的影响具有明显不同的特性。
The lining and the exterior fabric are actually produced as one integral layer, eliminating the need for additional adhesives or backings that can limit airflow.
