Comments on “Biot model of sound propagation in water-saturated sand” [J. Acoust. Soc. Am. 97, 199–214 (1995)]

Input parameters to the Biot theory, used by N. P. Chotiros [J. Acoust. Soc. Am. 97, 199–214 (1995)] in an effort to claim that a slow wave propagating at 1200 m/s was experimentally observed in near-bottom sand, are shown to be inconsistent with generally accepted results from prior theoretical and experimental studies of granular media.
