A number of endeavor studies on increase of the sound transmission loss of the fuselage panel is carried out. Optimum variants of the vibrodamping materials fastenings on a fuselage construction from the point of view of noise reduction into the aircraft are defined. The results showing essential increase of the sound transmission loss of the fuselage panel at a certain way of fastening of the interior panel in the wide range of frequencies are received. Techniques of carrying out such researches in reverberation rooms are fulfilled.
