| Abstract: | In this paper,inverse energy transmission in composite sound absorption structures mentioned in references 1] and 2] is investigated. By.inversion of transfer matrixes of the composite structures. relations describing the inverse transmission of sound energy and of vibrational energy are deduced. The transmission losses of sound intensity and of vibrational power per unit area are calculated. and their variations with the parameters of each structure layer are analysed. |
