En étudiant les propfans, l'équipe d'Airbus a conclu que les bruits engendrés par la turbine étaient négligeables par rapport aux bruits d'hélices et que parmi ces derniers, le bruit propre à chaque hélice créé par les propfans provient des interactions entre hélices, chacune «entraînant des fluctuations de portance sur les pales de l'autre hélices». Ces phénomènes engendrent les fameux lobes de bruit. 1, record 1, French, - lobe%20de%20bruit

Absence of noise. Perhaps the single most important factor in providing good hearing conditions is the absence of any interfering noise. Background noise... has no place in the room in which there is serious listening to speech or music. Not only must the air-handling system be inaudible, but there must be no noise transmitted from other spaces in the building or from outside.... 1, record 2, English, - absence%20of%20noise
