Elastic properties of different ice phases were studied in the low-temperature-high-pressure region (77<T<200 K, 0<P<2 GPa). The main attention was paid to the elastic characteristics of low-density (lda) and high-density (hda) amorphous H<SUB>2</SUB>O phases. Considerable softening of the transverse acoustic velocity and the corresponding shear modules G was found in the vicinity of lda-hda transition during both heating of the Ma phase and compression of the lda phase.
