To carry out this study we measure the correlation function of the trace of the energy-momentum tensor for a set of temperatures within the range $T/T_c \\in (0.9, 1.5)$. To extract the bulk viscosity from the correlation function we apply the Backus-Gilbert method and the Tikhonov regularization method. We show that the ratio $\\zeta/s$ is small in the region $T/T_c \\geqslant 1.1-1.2$ and in the vicinity of the transition $T/T_c \\leqslant 1.1-1.2$ it quickly rises.
