Many qualitative observations have been made on the quieting effect of newly fallen snow. This natural phenomenon must depend on the acoustical properties of such a layer of snow. While the physical constants for snow vary over a considerable range, and the data for obtaining some of the necessary acoustic constants are meager, the general behavior of a layer of snow as a sound‐absorbing material may be estimated. Particular attention is paid to the equivalent absorption at grazing incidence since much of the atmospheric transmission of sound occurs at small angles to the snow surface.
