The coefficient of absorption of ultrasonic waves in benzene was measured as a function of the temperature by means of the sonic interferometer. The frequency‐free coefficient varies from to over the temperature range from 7.2°C to 73.5°C. It appears that the absorption of ultrasonic waves in liquids is effected by two causes, viz., the viscosity effect deduced by Stokes, and a second effect of uncertain origin. In benzene, the second effect pre‐dominates overwhelmingly and determines the over‐all temperature dependence of the absorption coefficient.
