The theoretical research of reflection of bulk magnetoelastic waves in the ferromagnet with isotropic elastic properties has been investigated. It shows calculation of intensities of reflection and transmission of magnetoelastic waves at falling on the boundary of two semi-infinite uniform: ferromagnets with different values of parameters of exchange interaction, uniaxial magnetic anisotropy and saturation magnetization; Taking into consideration the coupling in the interface, which qualitatively changes the nature of frequency dependences of reflected magnetoelastic waves intensity and dependences on the external uniform permanent magnetic field.
