The velocity and absorption of infinitesimal plane sound waves have been measured in neon-helium, argon-helium and krypton-helium mixtures, with molar fractions of helium from 0 to 1 in each mixture The measurements were made at 25 c, at a frequency of 700 kc/s, and at pressures from 0 1 to 2 atm The observed velocity of sound was correlated with values calculated from simple mixture thermodynamics, the measured absorption coefficients agreed with those calculated from a formula derived by Kohler
