On the reciprocity relationship between direct field radiation and diffuse reverberant loading

@article{citeulike:898253, abstract = {This analysis is concerned with the derivation of a \"diffuse field\" reciprocity relationship between the diffuse field excitation of a connection to a structural or acoustic subsystem and the radiation impedance of the connection. Such a relationship has been derived previously for connections described by a single degree of freedom. In the present work it is shown that the diffuse\&\#150;field reciprocity relationship also arises when describing the ensemble average response of connections to structural or acoustic subsystems with uncertain boundaries. Furthermore, it is shown that the existing diffuse\&\#150;field reciprocity relationship can be extended to encompass connections that possess an arbitrary number of degrees of freedom.
