| Abstract: | In combination with SEA, this article, based on an analysis of the influence of the laying position of the acoustic layer on cabin noise, studies the influence of different dissipation factors on cabin noise, the results of which indicate that the changes of the damping coefficients have a great effect on the vibration damping and noise reduction of the acoustic layer. |
