Hybrid wave based - transfer matrix modeling of sound insulation problems KU Leuven
In this paper, a hybrid wave based - transfer matrix model is presented which allows for the determination of the sound insulation of multilayered structures placed between two rooms. The multilayered structure may consist of a number of panels separated by air cavities. The panels itself may consist of an arbitrary number of elastic and/or poro-elastic layers. The modal behaviour of the rooms and air cavities is taken into account by a wave ...
