The problem of identification and localization of sound sources inside industrial rooms, including cases when the density of sound sources is considerable, can be solved by application of inverse methods. The experimental knowledge about the distribution of acoustic field in the neighborhood of the examined object, followed by the reversal of the model used for sound generation and propagation, leads to evaluation of the object's acoustic power. For the cases when determination of the rooms' acoustical properties is required the combination of the inverse method with the boundary elements method allows the calculation of acoustic impedance for the surface delimiting the examined room. The paper presents the prospects of the inverse method application in the mentioned vibroacoustic problems.
