Abstract
The different (static and dynamic) aspects of the first-sound velocity near the lambda point in liquid 4He are simultaneously and consistently analysed in terms of the so-called specific heat approaches: the Pippard cylindrical-like approximations of the thermodynamic velocity and the Ferrell-Bhattacharjee approach of critical dispersion. This analysis also constitutes one of the very few existing quantitative checks of the general procedures used in comparing experiments and theories for any critical transport property. A strikingly good agreement with experimental results is found.
