In this paper we compare the experimental results and numerical simulations of the sound reduction index for several laminated glasses mounted onto a square 1.2m*1.2m window. We also justify that it is necessary to appropriately adjust the limit angle of the emitting room in order to optimize the numerical predictions. The difference between the values obtained for the numerical predictions and the experimental results are lower than 1 dB.
