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。
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.
