Objective Evaluation Model for interior Sound Quality Research

摘要：

In this paper, Programming developed a set of computable sound samples of four psychoacoustics objective parameters of the software program: loudness, sharpness, roughness, fluctuation strength base on Matlab platform. Though a group of noise signal of steady vehicle interior is collected by real vehicle that can be rapidly calculate various pa rameters of objective evaluation of the sound samples, and the results of ArtemiS software of Head Acoustics Company in Germany were contrasted and calibrated. The results showed that, the difference percentage of absolute value were all less than 6％ of both. The compiled programs of this paper has higher credibility and accuracy, sound quality can be used for an objective evaluation and analysis.
