A hybrid method is proposed to predict the noise radiated by vibrating structures in high frequency range. The transverse velocity of the vibrating structure is obtained by a low-frequency approach using modal analysis. From the knowledge of the surface vibratory field, some equivalent acoustical sources are introduced in order to involve the radiative transfer method. A closed-form relationship for the amplitude of these sources is proposed from the intensity field computed applying the

... cy average quadratic pressure approach. One example is considered to validate the method: the radiation of a simple supported baffled plate. Results are in agreement with reference ones. This method allows to predict the radiated noise in free-field conditions but also inside open or closed enclosures.
