This paper takes the 11 samples of interior noise in pure electric buses as the research object,re-duces the dimensionality of objective parameters by principal component analysis method,and then uses the reduced principal component as independent variables and subjective evaluation results as dependent varia-bles to construct a multiple linear regression prediction model.The results show that the average relative er-ror of the model is 4.6%,and the prediction results are reliable.
