The combinations one can build up are nearly infinite since there are so many frame types and panels that can be varied. This is a reason for why prediction tools in acoustics are necessary for lightweight walls so that the sound insula-tion performance of a specific combination of frames and panels can be estimated.
An analytical model, based on wave propagation theory for layered medium, has been developed to predict the airborne and impact sound insulation provided by single and multilayer systems of infinite extent, neglecting sound bridges and flanking transmission .

1. Introduction The first engineering theories of airborne sound transmission via single and double walls were developed for uniform partitions of infinite area by Cremer in 1942 [1] and London in 1950 [2]. For single partitions at low frequencies, the theoretical sound transmission loss was described by the Mass Law as a function of the surface density, frequency, and incident sound field ...
This paper concerns the development and validation of numerical models using Finite Element Methods (FEM) to predict airborne sound transmission in Cross Laminated Timber (CLT) floors. Vibroacoustic finite element models of a simply supported three-layer CLT panel were developed in COMSOL and validated against airborne laboratory measurements.
