Abstract: This paper reports some measurements of the noise environment at various service states of aircfafts, the obtained acoustic loading distribution and frequenocy spectra of the structure a preliminary analysis of the factors effecting the magnitude of parameters concerned and acoustic vibration response characterstics of structure, a brief summary of acoustic loading spectra and detailed description of the method for drawing them up based on the combination of practical measurements with statistical investigation, a brief introduction to the method for testing acoustic fatigue and principles for selecting parameters through an example of acoustic fatigue test on a full-scale fuselage inlet, and finally, a recommendation for analysis and remedy of acoustic fatigue troubles, It also provides a data basis and a practical example for investigating the mechanism of acoustic fatigue, res-ponse characteristics of structure to acoustic loading and the control method for preventing acoutic fatigue failure of structure :
