Abstract: We examine the behavior of sound attenuation and bulk viscosity near the 2'nd order QCD phase transition at finite density. A dynamical model is presented describing the coupled evolution of sound mode and a slow mode of fluctuations.<br />Comment: 4 pages, 1 figure, contribution to the proceedings of the Rencontres de Moriond 2018 on QCD and High Energy Interactions
