The calculation procedure of Aures roughness model is discussed in' detail. The basic principle and calculation skills of the algorithm are described. Some points that can easily lead to errors are pointed out and discussed in detail. Then the algorithm is implemented with MATLAB. And the roughness of typical signals is calculated. The results are compared with the experimental data of Zwicker and S. Kemp and the numerical data from NI' s calculation modulus. The correctness of the algorithm is verified.%详细论述Aures粗糙度模型的计算过程,阐述算法的基本原理和计算技巧,指出一些容易导致错误的细节问题.利用Matlab实现算法,并计算典型信号的粗糙度.将计算结果同Zwicker、S.Kemp的试验数据以及NI计算模块的结果进行对比,论证计算方法的正确性.
