The invention relates to a simulation system for laboratory testing of enclosed cabin parts which are used in the form of rest rooms and are mountable in commercial aircrafts. According to said invention, a cabin part is raised by means of vibrators for simulating the noise of a structure corresponding to the future connection to a fuselage structure. The elements producing airborne noise are also connected to said cabin part. The vibrators and the airborne noise producing elements are adjustable with the aid of adjusting and control devices. Signals are produced through a computer unit provided with input data files based on possibly extrapolated acoustic values of the assembling area and the design of said cabin part.

La présente invention concerne un système de simulation pour l'essai en laboratoire de parties de cabines fermées destinées à servir d'espaces de repos et à être montées dans des avions de ligne. Selon la présente invention, la partie de cabine est montée à l'aide de vibrateurs pour la simulation d'un bruit de structure correspondant à la liaison ultérieure à la structure de fuselage. Des éléments de production de bruits aériens sont en outre associés à la partie de cabine. Les vibrateurs et les éléments de production de bruits aériens peuvent être réglés à l'aide d'appareils de réglage et de commande. Les signaux sont produits via une unité informatique avec fichier d'entrée de données basées sur des connaissances ainsi éventuellement que par extrapolation des valeurs acoustiques sur l'emplacement de montage et de la conception de ladite partie de cabine.
