"Results from field measurements as well as numerical computations of sound transmission (""Green´s functions, noise transfer functions"") for air-borne sound for some typical installations."

For the equivalent monopole method the transmission is exactly described by a so called Greens function ie a measurement or simulation of the frequency response between a monopole source strength and acoustic pressure at a receiving point Field measurements will be performed of Greens functions for a few selected cases on rail vehicles standstill conditions and used to validate the numerical models provided by ISVRVTC
