Abstract

This study investigates the frequency-specific performance of modelled acoustic attenuator using finite element methods (FEM) to model transmission loss (TL) and insertion loss (IL). Addressing gaps in mid-frequency optimization and computational efficiency, the Helmholtz equation was parameterized under realistic boundary conditions, with iterative mesh refinement enhancing accuracy. The attenuator achieved a peak TL of 26.6 dB at 630 Hz and IL of 9.3 dB at 1260 Hz, demonstrating high efficiency in mid- to high-frequency noise suppression. The findings advance scalable design methodologies, offering valuable insights into frequency-dependent acoustic behavior and practical solutions for diverse noise control applications.
