[Abstract]With 8 noi samples of wiper system acquired as object，three main nsory con-stituents of wiper system noi （ motor noi，direction reversal noi and blade scraping noi），which can de-scribe the operation status of wiper system，are subjectively identified by human ears.Through multivariate regression analysis哺乳期可以吃蒜吗，the objective evaluation model for the sound quality of three noi constituents is t up and finally an evaluation model is established using the annoyance degrees of three noi components to characterize the overall sound quality of wiper system noi.
