Description

Ce projet est une réponse à la reconnaissance que le niveau de bruit est l'un des facteurs principaux de la perception du confort par les passagers, dans les avions et hélicoptères.

This project is the response to the recognition that the noise level is one of the most important factors contributing to the passenger perception of cabin comfort, in both fixed wing aircraft and helicopters.

Objectifs/Objectives

À l'aide d'outils de simulation de pointe, le projet a pour objectif d'analyser l'environnement acoustique dans la cabine d'avions et d'hélicoptères et de diminuer le bruit à l'aide de techniques novatrices (nouvelles configurations ou matériaux, contrôle actif).

Its main objectives are:

-To provide the industry with state-of-the-art simulation tools to analyse the acoustic environment of aircraft
-To investigate innovative passive techniques to reduce cabin noise (such as new acoustic material and trim configurations),
-To develop innovative active control techniques to reduce structure-borne sound inside helicopters

Project 2.2 Wrap-up Meeting

2006-12-20 - University of Sherbrooke

In good spirit and an atmosphere of work well done, the project partners met one last time to wrap-up. All deliverables have been met successfully and on schedule. With the industrial partners highly satisfied, the research has led the way to 3rd round CRIAQ projects.
