Query: Sound transmission loss through double glazing windows in low frequency
  range   The domestic windows in the exterior building facade play a significant role
in sound insulation against outdoor airborne noise. The prediction of their
acoustic performances is classically carried out in laboratory according to
standard ISO 10140. In this work, a 3D elasto-acoustic finite element model
(FEM) is proposed to predict the sound reduction index of three different
glazing configurations of domestic window, which are compared to laboratory
measurements. Two acoustic cavities with rigid-boundaries on both sides of the
window are used to simulate respectively the diffuse field on the source side
and the pressure field on the receiver side. By using a simplified FEM for the
double glazed windows, the sound reduction index is calculated from the
difference between the source and receiving sound pressure levels in the
one-third octave band from 100 to 500 Hz.
