Before revision:  Here we investigate how the dynamics of the solvation shell changes for molecules embedded in lipid membranes during an acoustic impulse . Solvation sensitive fluorescence probes, Laurdan, embedded in multi-lamellar lipid vesicles in water,  were exposed to broadband pressure impulses of the order of 1MPa peak amplitude and 10{\mu}s pulse duration.
