The turbulence impinging on an airfoil generates aeroacoustic noise, also referred to as leading-edge noise, which plays an important role in industrial sectors such as wind energy, aviation and cooling/ventilation. For its mitigation, one of the proposed solutions involves the integration of porous materials into the structure of the wing profile. Since the physical mechanisms responsible for the noise reduction have not been defined yet, the aim of this work is to investigate how porosity affects the surface-turbulence interaction and the evolution of the wall-pressure fluctuations radiating into the far field to provide new information for a better understanding of this phenomenon.
