Abstract

Abstract: 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.
