We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering, while the noise frequency correlation function determines the diffusion constant. The quantum noise observables are found to scale markedly diff...

The sound field radiated by a wind turbine changes significantly with propagation distance, depending on the meteorological conditions and type of ground. In this article, we present noise synthesis model which is based theoretical source models.
