At rather low temperatures snow is characterized by three 
velocities of sound, two of which are related to propagation of longitudinal 
and transverse waves through a solid skeleton formed by ice crystals 
and the third of which is related to propagation of longitudinal waves 
through air in snow pores. The main laws governing propagation and 
absorption of these waves are determined. Analytical formulas that 
express the dependence of the coefficient of attenuation of waves 
on frequency are obtained.
