We theoretically investigate the cooling of a propagating phonon through Brillouin scattering. To that end, we propose to introduce an external viscous force using Brillouin scattering and an electro-optic feedback. Short delays feedback show an efficient control of the Brillouin linewidth whereas long delays can induce Fano-like resonances.
