真丝绸摩擦振动声响特征分析

ANALYSIS OF THE CHARACTERISTIC OF THE SILK FABRIC FRACTIVE VIBRATION SOUND

本文主要对丝织物间的摩擦振动声进行了初步的研究，并试图找出真丝绸特有的丝鸣特征。将不同原料，经过不同处理的两块织物在一定条件下摩擦发声，将摩擦声进行频谱分析和波形分析。根据实验结果可得，经酸处理的真丝织物具有明显的倍频效应，且频率在６～８ＫＨｚ问的振动亦较化纤织物为多。

his article is about the elementary reach of the silk fabric sounel, and trying to find the especial characteristic of the silk sound.The two pieces of the cloth, which were made of different material or treated in different ways, rubbed together in the certain conditions.The fricative was then analysed with the frequency sore and wave shape.It can be known from the experimental results that the real silk fabric which was treated with acid has more evident multiple-freqency than the syhthtic fabric and its fricative which frequency is between 6～8KHz is much more than that of the synthetic facric.
