Design of a Kelvin cell acoustic metamaterial
(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 ... -
Fan-noise reduction of data centre telecommunications' server racks, with an acoustic metamaterial broadband, low-frequency sound-absorbing liner
(2023)An acoustic metamaterial is evaluated successfully as a means to reduce axial fan noise in an IT server rack application. The continuing growth in demand for cloud-based memory storage is outpacing sustainable energy ... -
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 ... -

Multi-chamber micro-perforated panel absorbers optimised for high amplitude broadband absorption using a two-point impedance method
(2023)An optimised, multi-chamber, micro-perforated panel absorber (MC-MPPA) with micro-perforated adjoining panels is presented in this paper. An MPPA is a clean and efficient noise absorber with a simple structure making it ...
