The invention belongs to the field of automobiles, and discloses a sound evaluation design method for an automobile skylight sunshade curtain system. The method comprises the following steps: 1, objectively testing the sound of a skylight sunshade curtain system in a whole vehicle state; 2, based on the test in the step 1, performing primary selection of objective evaluation parameters according to psychoacoustics; 3, based on the objective evaluation parameters primarily selected in the step 2, subjective evaluation of the sound of the skylight sunshade curtain system in the whole vehicle state is carried out; 4, based on the subjective evaluation in the step 3, correction parameters are calculated according to psychoacoustics; 5, based on the parameters corrected in the step 4, subjective and objective parameter correlation analysis is carried out; and step 6, establishing a subjective and objective evaluation target system based on the analysis of the parameter relevance in the step 5. The method is used for solving the problem that in the prior art, the subjective and objective perception matching precision is not improved through correction of acoustic parameters in the skylight opening state.
Description
technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a sound evaluation and design method for a sunroof sunshade system of an automobile. Background technique [0002] As the automobile industry matures, the sound design of the auto parts system will gradually develop from the early noise reduction to the improvement of sound quality. The development of sound quality will inevitably introduce psychoacoustic parameters different from the traditional sound pressure level. Different psychoacoustic parameters have different applicable working conditions, so the first step of this patent is to determine the psychoacoustic parameters suitable for describing the sunroof sunshade. Consider that the open state of the sunroof is a different acoustic perception environment for the occupants of the vehicle compared to the closed state. Therefore, the next step is to introduce the corresponding corrections to unify the psychoacoustic pa...
