摘要
用极点-零点模型和模态理论研究声学系统和振动结构的相位特性,并通过将极点-零点模型及波动传播理论的相位估计与试验结果的比较,指出了这两种估计方法的适用性和局限性。
This paper studies the phase characteristics of transfer functions of vibration structures in the complex -frequency domain,by using Pole -Zero model and modal theory,compares the test results with the estimation of reverberant phase limit,wave propagation phase and measured phase spectrum,and points out the applicability and limit of the estimation.
