Experimental results, obtained at low frequencies for the coefficient of a sound scattering in a subtropical part of Pacific ocean are discussed. Received in experiment the spectrum with a power parameter n=1,4 testifies that the frequency dependence does not appropriate neither of early known models of sound scattering, but it is easy explained by the assumption of a fractal structure of inhomogeneities in ocean with dimension D=1,4. The latter in accuracy corresponds to situations, considered by Lysanov and Lyamshev, and confirms the new concept fractal offered by them for the explanation of scattering and attenuation of a sound in ocean at low frequencies.
