Noises inside a cockpit and a cabin and airborne and structureborne noise are summarized with the use of graphics. The necessity of having a model of acoustic and vibration transmission is outlined. The history and complexity of models, fuselage test in laboratory and a comparison of theory and experiment are discussed. The modal method is concluded to give a good understanding of the transmission phenomena through an aircraft fuselage in a 0.15 to 2.3 frequency range. The ease of use of these methods allow parametrical studies for preliminary design for noise reduction purpose.
