Acoustic properties of profiled cladding on buildings
This paper presents a theoretical model to analyse the acoustic properties of profiled cladding which is found on the facade of many buildings. The cladding is modelled as a periodic structure consisting of long narrow individual panels attached to each other. Hamilton's principle is used to calculate the amplitudes of different wave types (bending, compressional) on the individual panels. The wave types are coupled to each other at the edges of each panel. This is modelled by suitable boundary conditions. Bloch's theorem is used to describe the periodicity of the cladding. The model predicts the wave numbers and decay rates of structure-borne waves along the cladding, predicts the sound transmitted by claddings, and suggests designs of cladding that reduce sound transmission from buildings into the environment.
