A 3D printed acoustic metamaterial liner to reduce low-frequency aeroengine noise
(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 ... -
The influence of additive manufacturing processes on the performance of a periodic acoustic metamaterial
(2019)Advancements in 3D print technology now allow the printing of structured acoustic absorbent materials at the appropriate microscopic scale and sample sizes. The repeatability of the fundamental cell unit of these metamaterials ...
