Acoustical topology optimization for Zwicker’s loudness model – Application to noise barriers
TL;DR: In this paper, a design method for acoustical topology optimization by considering human's subjective conception of sound is presented to minimize the main specific loudness of a target critical band rate by optimizing the distribution of the reflecting material in a design domain.

Design of a local resonator using topology optimization to tailor bandgaps in plate structures
TL;DR: In this paper, a topology optimization method for a local resonator is presented to tailor flexural bandgaps in plate structures in order to tailor the bandgap at the desired frequency range.

Acoustical topology optimization of Zwicker's loudness with Padé approximation
TL;DR: In this paper, the authors proposed a computationally efficient approach to resolve the computational issue in the computation and optimization of Zwicker's loudness, which combines the finite element method (FEM) with the Pade approximation (PA) procedure.

Sound transmission analysis of plate structures using the finite element method and elementary radiator approach with radiator error index
TL;DR: The accuracy and efficiency of the proposed FE-ERA method are validated by comparison with the results of the three dimensional (3D) FEM structure-acoustic interaction models.

Topology optimization of bounded acoustic problems using the hybrid finite element-wave based method
TL;DR: In this article, a gradient-based topology optimization method that uses the hybrid finite element-wave based method (FE-WBM) is proposed for bounded acoustic problems, where the entire domain of a problem is partitioned into design and non-design domains.
