| GAA | Metamateriales aeroacústicos para sistemas de transporte más silenciosos y energéticamente eficientes Low frequency noise sources are increasingly present in guided flows, particularly in aeronautics where new engine architectures are driven by the reduction of energy consumption. Current acoustic treatments present a conflict between achieving both high acoustic and aerodynamic performance while respecting the constraints of reduced lined surface, low thickness and low embarked weight. |

| GAA | ECOFAN: Revestimientos aeroacústicos mejorados para el diseño de ventiladores de sistemas de refrigeración y de climatización Energy efficiency has been identified as one of the key pillars of decarbonisation in the Net Zero Emissions by 2050 roadmap. It should be specially considered for the development of sustainable cities, as almost 80% of the population lives in towns and consumes 78% of the primary energy. It is estimated that buildings account for 20% to 40% of the total energy consumption in developed countries. |
| GAA | Reduction of acoustic and aerodynamic noise through sustainable micro-pore absorbers Land transport and aeronautical industries are currently faced with the challenge of the design of lightweight and compact acoustic materials capable of reducing under flow the low and medium frequency components (< 1 kHz) of surrounding noise sources. |
| GAA | Absorción acústica cuasi-perfecta en banda ancha con metamateriales bio-inspirados para los sistemas de transporte terrestres y aéreos Aircraft noise has become a major concern for communities around airports giving rise to stacked legislations and regulations at various levels. Current noise reduction technologies do not seem to achieve the targeted reductions set by the EC experts by the ACARE Flightpath 2050. |
