Accounting for modal behaviour in the prediction of sound transmission through simply supported building elements using periodic structures theory KU Leuven
In order to optimize the sound insulation of building elements, efficient and sufficiently accurate prediction tools over a broad frequency range are required to avoid extensive experimental prototype testing in an acoustic laboratory. When simulating the transmission suite, a hybrid framework can be used to divide the room-wall-room system into statistical and deterministic subsystems. While the rooms are assumed to have diffuse sound fields ...
