Query: Radiation attenuation of bend oscillations of coherent martensitic and
  twin boundaries   In frameworks of the macroscopic dynamic theory of coherent interfaces in
crystals the acoustic radiation of coherent boundary at passage along it of
localized wave packages is considered. It is shown that the coherent twin
boundary of acoustic waves does not radiate.
