✦ Synopsis

The kinetic theory of first sound in a quantum liquid is presented. The results for velocity and sound attenuation are obtained and found to be valid over a wide range of frequencies, including hydrodynamic, kinetic, and intermediate regimes, and throughout the whole temperature range in which a quasiparticle description is applicable. Comparison of theory and experiments is carried out.
