Based on their pressure-dependent measurements (by a torsional\noscillator technique), we propose that the {\\it supersolid} fraction\n($\\rho_s/\\rho$) might be relevant to an sound absorption or attenuation\n(fluctuations of pressure waves) in microscopic domain since there is no\napparent change in $T_c$ with pressure.",
