Abstract :
To analyze the influence of the amplitude of different frequency bands of vehicle interior noise on subjective evaluation, an orthogonal array table was designed with 12 factors and three levels using the design of experiment (DOE) method. Furthermore, the range analysis was presented, and the optimal combinations for different categories were found. The sound quality can be improved by increasing, decreasing, or keeping the sound pressure level (SPL) in a certain frequency band.
