Sammanfattning

The sound transmission in double walls at low frequencies is studied using a detailed geometric model, based on FEM. The model simulates the experiments carried out to determine the sound reduction index of the wall. The wall properties effect on the sound transmission loss is investigated and also how the sound reduction is affected by the dimensions of the connecting rooms.
