  The kinetic Ising model in a weak oscillating magnetic field is studied in
the context of stochastic resonance. The signal-to-noise ratio calculated with
simulations is found to peak at a nontrivial resonance temperature above the
equilibrium critical temperature T_c. We argue that its appearance is closely
related to the vanishing of the kinetic coefficient at T_c. Comparisons with
various theoretical results in one and higher dimensions are made.
