摘要
提出了一种非均匀介质中宽带信号的混响仿真模型,给出了简要的理论介绍、具体的实现方法和相应的仿真结果。它是基于声波的射线传播理论和单元散射理论,通过模拟海面、海底以及体积混响的物理形成过程实现混响仿真。
This paper presents a new model of reverberation spectrum emulation in non-uniform medium.Base on theory of the ray transmission and element scattering,reverberation spectrum emulation is the process of simulating reverberation formation physical process.This technique have the character of easy realization and good effectiveness.
