A noise control program is described and related first results are presented. Experimental results include selected test data of systematic transmission loss and noise reduction measurements performed on different aircraft fuselage panels and a full scale Dornier 328 test section, respectively. Theoretical results comprise vibration analysis data of fuselage sections of different designs as well as interior noise and related noise reduction spectra predicted for the full scale fuselage test section and the overall aircraft cabin structure. The results were obtained using a finite element code and a propeller interior noise program. Results are in good agreement and provide important inputs for an acoustical tuning of the fuselage structure. Information on the complex vibro-acoustic behavior of the aircraft cabin cavity and the fuselage structure is provided.
