    The problem of spectra for acoustic type of turbulence generated by shocks being randomly distributed in space is considered. It is shown that for turbulence with a weak anisotropy, such spectra have the same dependence in k -space as the Kadomtsev-Petviashvili spectrum: E (k) ∼ k-2. However, the frequency spectrum has always the falling ∼ ω-2, independent of anisotropy. In the strong anisotropic case the energy distribution relative to wave vectors takes anisotropic dependence, forming in the large- k region spectra of the jet type.
