Research areas description
This research program will propose breakthrough acoustic technologies integrated into engines and fuselage interior panels. It is structured around four main objectives:
- Develop a multi-scale method to design effective acoustic materials, from representative unit cells (micro) to complex systems operating in realistic environments (macro);
- Develop phenomenological models that correlate the microstructure of unit cells with the mechanical properties of the acoustic material as measured under operational conditions;
- Develop robust and reliable manufacturing processes and deliver fully functional prototypes; and
- Assess the real-world impact of noise control measures on the environment.

Specialized equipment
The Chair relies on the infrastructure of the Laboratory for Vibration and Acoustic Analysis (LAVA) at Polytechnique Montréal. Our architected materials are produced using our 3D printer and foaming equipment. Acoustic characterization of samples is carried out using impedance tubes, tortuosimeters, QMA, etc. A fully anechoic room and a reverberation chamber allow the evaluation of acoustic performance on representative-sized specimens. The equipment also includes shakers, sensors and instruments necessary for vibration testing, modal analyses and fatigue studies.

L'écart entre les sexes en génie: aller au-delà des chiffres
Le programme Folie technique de l'école de génie Polytechnique Montréal permet depuis 28 ans à 20 000 enfants par année de participer à diverses activités, dont un camp d'été. Retour d'Annie Ross, professeure titulaire au Département de génie mécanique.

Des étudiants et chercheurs de Polytechnique Montréal ont pour projet de construire de nouvelles pièces d’avions de ligne permettant de réduire leur poids, diminuer le bruit et limiter la pollution atmosphérique. « L’objectif du projet est de trouver de nouveaux matériaux pour réduire l’impact sonore, autant à l’intérieur des avions qu’à l’extérieur », explique Annie Ross, professeure titulaire au Département de génie mécanique de Polytechnique Montréal.
