摘要：

This work presents the design, optimization and combination of fully parameterized Archimedean spiral cavities (ASCs) as acoustic resonators, in order to achieve perfect absorption at frequencies below 1000 Hz while using a completely modular design. The assembly of two ASCs in the same system is also presented. An optimization is performed and results are verified through Finite Element Analysis (FEA) and validated experimentally for almost perfect absorption peaks at 700 Hz and 800 Hz. A good agreement is achieved between theory, simulation and experiments. (C) 2020 Elsevier Ltd. All rights reserved.
