    • 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 ...

    • Design of a Kelvin cell acoustic metamaterial 

      Kennedy, John; Rice, Henry; Trimble, Daniel; Göransson, Peter; Dowling, Luke (2020)
      Advancements in 3D print technology now allow the printing of structured acoustic absorptive materials at appropriate microscopic scales and sample sizes. Optimisation of parameter sets associated with a Kelvin Cell structure ...

    • Development of localised process parameter control for repeatability in metal additive manufacturing 

      Dowling, Luke Patrick (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2021)
      Due to the many advantages associated with metal additive manufacturing (AM) processes, research into these technologies has grown significantly over recent years. However, repeatability and reproducibility are critical ...

    • The Impact of Additive Manufacturing on the Acoustic Performance of Novel Porous Materials 

      Ciochon, Agnieszka Helena; Kennedy, John (2022)
      Commonly used conventional acoustic porous materials suffer from a limited operational frequency range and great dependency of the sample thickness on their performance. For this reason, acoustic metamaterials have caught ...
