Critical superflow, preceding a free ringing superfluid oscillation, induces a remnant stochastic uncertainty in the oscillation amplitude. We demonstrate that the distribution function for the oscillation{close_quote}s velocity amplitude reflects both the quantized size of the underlying phase-slip dissipation events, as well as the stochastic nature of the processes which nucleate the slips {copyright} {ital 1997} {ital The American Physical Society}
