N2  - We review recent calculations of quasinormal modes and asymptotic tails of the Bardeen spacetime interpreted as a quantum corrected Schwarzschild-like black holes. Massless electromagnetic and Dirac fields and massive scalar fields are considered. The first few overtones are much more sensitive to the change of the quantum correction parameter than the fundamental mode because such correction deforms the black hole geometry near the event horizon. While the asymptotic tails of massless fields are identical to those for the Schwarzschild case, the tails for a massive field differ from the Schwarzschild limit at both intermediate and asymptotic times.
