Line Source and Site Characterizations for Defining the Sound Transmission Loss of Building Facades
An analytical model is presented for defining the sound transmission loss of building facades exposed to noise from line sources. The model describes the non-diffuse sound field incident upon the facade in terms of both source and site parameters. The effects of facade orientation relative to the line source and the sound propagation with distance are introduced as a single term in the definition of the facade sound transmission loss. This term defines a mean angle of incidence for the exterior sound field that is equivalent to a point source location relative to a point on the facade. Numerical results are presented estimating the magnitude of these effects and it is shown that alternate methods for conducting field measurements of building facade sound transmission loss may be related using this model.
