An analysis of instability waves excitation in a two dimensional weakly inhomogeneous boundary layer on a vibrating surface is presented. Asymptotic expression is obtained for the amplitude of a Tollusin-Schlichting instability wave in the resonance case when the frequency and length of the wave that characterize the vibrating surface coincide with the corresponding parameters of the unstable excitation at the point of stability loss. Numerical results are presented for a vibrating heated film the flow of a compressible gas.
