An estimation of the response of panel structure under acoustic loads is based on the linear vibration theory and research of the dynamic response of panel structure.The joint acceptance has been used to consider the relative effect between the acoustic wavelength and the structure modal wavelength.The method is able not only for a single panel but also for complexity panel structure.This method is based on modal analysis

and the contribution of each modal is taken into account.The coupling degree between acoustic wave length and structure modal wavelength is considered

finally the total response spectrum of panel structure has been obtained.
