Frequency dependence of amplitude of transverse acoustic wave in antiferromagnetic monocrystal iron borate was investigated. It was shown that experimental amplitude-frequency characteristics may be interpreted on the basis of developed theory of magnetic birefringence of sound in FeBO3 taking into account defect structure of the real crystal, experimental boundary conditions and pass band of piezotransducers.
