A Comparison of the Sound Transmission of Profiled Metal Cladding When Measured in the Laboratory and in Situ

Work is currently being undertaken at the University of Salford to develop a noise prediction scheme which should enable design engineers to accurately predict environmental noise from proposed industrial constructions.This project involves an analysis of many acoustical topics; from a consideration of the internal sound field (e.g. using ray-tracing) , through the transmission and directivity of various building elements, to considerations of meteorological and outdoor propagation effects such as wind and temperature gradients, screening and the ground effect.
