Neck shape optimization of resonator-type sound absorbers using adjoint lattice Boltzmann method

Resonant sound-absorbing devices, such as Helmholtz resonators, can effectively reduce discrete frequency noise radiated from various engineering equipment. In this study, we attempted to improve the sound absorption characteristics of a Helmholtz resonator using an unsteady adjoint method based on...
