Abstract :
The STSF method (Spatial Transformation of Sound Fields) is extremely versatile in the way that any acoustical parameter (pressure, velocity or intensity) can be estimated in the half space in from of the noise object. This allows simulation of attenuation of noise sources on the surface of the noise object, and the effect in the far field can be estimated.
