Résumé

In this article the problems of vibroacoustics of new generation aircrafts are considered. Analyzing the noise sources of new generation aircrafts with high and superhigh bypass-ratio engines, its spectral distribution, new investigations on noise reduction, an attempt was made to consider the problem of noise reduction broader than only community noise.
