A human ear simulation model for noise classification

Reference-Scale Estimation method based on paired comparison is one of sound quality subjective evaluation methods. This method needs to use the paired comparison method to sequence all of sound samples and to establish standard noise sample before magnitude estimation. This process is very cumbersome with great labor intensity. In order to eliminate this step, a human era model was proposed to achieve preliminary noise classification and establish reference noise sample automatically. 24 noise samples from 8 driving cycles of a fuel cell vehicle (FCV) were chosen as examples to introduce the main theory and prove its effectiveness.
