  • 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 ...

  • Fan Noise Reduction using Acoustic Metamaterials towards Efficient Data Centers 

    Wasala, Sahan (2022)
    Unwanted sound from cooling fans has been a significant obstacle that limits the performance of data center Hard Disk Drive (HDD) storage systems. Acoustic metamaterials (AM) can be a solution to this problem. AM’s can ...

  • Plate-type Acoustic Valve Resonator for, Low-frequency Sound Absorption 

    Hossain, Md Robiul (Trinity College Dublin. School of Engineering. Discipline of Mechanical & Manuf. Eng, 2024)
    Plate-type acoustic metamaterials with deep-subwavelength thickness have generated considerable enthusiasm for addressing low-frequency noise. These metamaterials can be tailored to obtain high absorption efficiency by ...
