中文摘要:
      环境声质量是近年来环境声学的前沿方向,已有的研究主要是针对单一噪声烦恼度的定量评价。而实际中常见的环境噪声是多个单一噪声叠加的混合噪声,因此有必要对混合噪声的评价进行研究。文章主要通过对已有的混合噪声烦恼度评价方法的研究,将基于Zwicker声质量评价理论的烦恼度计算公式应用于混合噪声烦恼度的评价,尝试提出一种基于人耳听觉特性的混合噪声烦恼度的评价模型,编制了相应的程序,对其中的典型情况进行了计算机仿真。
英文摘要:
      Environmental sound quality is an important research topic in acoustics.Existing work is mostly focused on evaluating the degree of annoyance caused by a single noise source.In practice,however,commonly encountered environmental noise is a mixture of sounds due to multiple sources.It is therefore necessary to study mixed noise.In this paper,evaluation of typical mixed noise is studied.A formula measuring the degree of annoyance based on Zwicker's sound quality theory is applied to evaluate combined noise.An improved model is proposed.Some typical instances are simulated with a computer program designed to calculate the parameters of the model.
