Recent studies about collisionless shocks in partially ionized plasmas showedthat some of neutral particles leak into the shock upstream region from thedownstream region. In this paper, we perform a linear analysis and show thatacoustic waves are unstable in the neutral precursor region. The acousticinstability amplifies fluctuations of magnetic field and density in theupstream region. The fluctuations are indispensable for the diffusive shockacceleration and could be important for the downstream turbulence.
