dc.description.abstract | Shape optimization of a duct system with respect to sound transmission loss
is considered. The objective of optimization is to maximize the sound transmission
loss at multiple frequency ranges simultaneously by adjusting the shape
of a reactive muffler component. The noise reduction problem is formulated
as a multiobjective optimization problem. The sound attenuation for each considered
frequency is determined by a hybrid method, which requires solving
Helmholtz equation numerically by finite element method. The optimization is
performed using non-dominated sorting genetic algorithm, NSGA-II, which is a
multi-objective genetic algorithm. The hybrid numerical method is flexible with
respect to geometric shapes, material parameters and boundary conditions. Its
combination with multiobjective optimization provides an efficient method to
design muffler components. | |
