  • A 3D printed acoustic metamaterial liner to reduce low-frequency aeroengine noise 

    Ross, Eoghan Paul (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2023)
    As the level of air travel continues to increase, so too does the demand for better noise-reduction technologies for aircraft. The environmental noise produced by aircraft has been shown to have a significant adverse effect ...

  • Predictions of Rotor Broadband Noise 

    Botha, Jason (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2018)
    This thesis presents an enhanced method for predicting aerodynamically generated broadband noise, produced by rotating machinery. The method improves on existing work for Vertical Axis Wind Turbine (VAWT) noise prediction, ...
