Titel
Reduction of the noise transmission through a double glazed window due to adaptive measures
Abstract
In this work the sound transmission through a double-glazed window is reduced due to adaptive methods with a focus on an adaptive Helmholtz resonator acting on the sound field in the air gap between the two glass plates. As test-rig a double glazed window is mounted on a rectangular cavity. The system is experimentally characterised and simulated using the commercial numerical software ANSYS. In termes of the noise transmission the gained model is reduced using model order reduction techniques and transferred to MATLAB/Simulink. Evaluating the transmitted noise the radiated sound pressure is calculated using the acoustic monopole synthesis.
