| Summary: | 碩士 === 國立臺灣海洋大學 === 系統工程暨造船學系 === 102 === The first purpose of this paper is to study the shu shu sound noise of two pull sliding window when it partially opened with varying size. The resonating phenomenon of airflow noise will be happened when the airflow pass through middle of cavity windows between two pieces of glass. We try to improve resonance frequency of the changing window cavity using Helmholtz Resonator concepts. Before the simulation we used the COMSOL Multiphysics FEM simulation software to verify some scenarios and methods, which I propose it. The result of the Helmholtz Resonator design to control the resonating noise of airflow shown that can be reduced. We also take others control methods. The noise reduction results are also discussed after a series of experiment..
