Temperature evolution of relative acoustic speed and logarithmic attenuation in Sr0.61Ba0.39Nb2—xO6:Crx3+ single crystals with tetragonal tungsten bronze structure (x = 0.0, 0.005, 0.01) was determined. In the phase transition region and in the low temperature region were revealed anomalies in the acoustic parameters behavior. These anomalies are considered with standpoint of the structured change, occurring in system SBN doping by Cr.
