Reliability analysis of different geometric configurations of Helmholtz resonators for a sustainable performance (opens in new tab)

A Helmholtz resonator (HR), consisting of a cavity connected to a neck, is widely used for noise control at a specific tuning frequency determined by the neck cross-sectional area and length, cavity volume, and speed of sound. Uncertainty in geometric parameters and air properties can significantly influence the tuning frequency and transmission loss, thereby affecting HR performance. In this study, finite element analysis is employed to optimise the geometry of an HR integrated with a duct s...
