International audienceA hybrid method is proposed to study the noise radiated in the high frequency range by a gearbox inside an engine compartment. Due to its elastodynamic characteristics, the vibratory behaviour of the transmission lies in the low frequency range. However, the noise radiated is rather in the high frequency range facing the size of the acoustical cavity. Thus the proposed hybrid method allows to couple a modal approach for the vibratory predictions (spectral iterative method) to a high frequency acoustical approach which leads to reduced computational times compared to the classical boundary element methods (radiative transfer method). The coupling is realized trough equivalent energy sources introduced on the surface of ...
