Abstract: | Two different models have been derived in order to compute sound transmission through opened windows. The first model is a hybrid model which combines modal, geometrical, wave and integral approaches. The second model is a multi-domain BEM approach which is used as a reference. Comparisons have also been made with published measurements. Numerical aspects are discussed. SEA computations are used to compute structure born transmission in order to verify the predominance of acoustical transfer through the windows. |
