  Evolution of gravitational perturbations, both in time and frequency domains,
is considered for a spherically symmetric black hole in the non-reduced
Einstein-Aether theory. It is shown that real oscillation frequency and damping
rate are larger for the Einstein-Aether black hole than for the Schwarzschild
black hole. This may provide an opportunity to observe aether in the
forthcoming experiments with new generation of gravitational antennas.
