The frequency spectra of acoustic losses in <100> oriented
KCl crystals have been studied in the frequency range 7.5 to 232.5 MC
at temperatures from 77 to 300 K. Proceeding from those spectra,
the temperature dependence of viscosity coefficient, B, has
been determined. The dependence has been compared with theory and
the data obtained by other experimental methods.
