本文从声学的基本理论出发,研究了蚕丝吸声的微观机理。计算了蚕丝的中空管道的声阻和声吸收系数。得到的结论是:由于蚕丝具有槽钢状的中空管道,使它有良好的吸声性能。
Based on the basic theory of acoustics, this paper studies the microscopic mechanism of silk acoustic absorption. The acoustic impedance and acoustic absorption coefficient of the hollow pipe of silk were calculated. The conclusion is: Because silk has a hollow steel channel, it has good sound absorption performance.
