In this paper we investigate scalar perturbation over a Frolov black hole(BH),which is a regular BH induced by the quantum gravity effect.The quasinormal frequencies of a scalar field always consistently reside in the lower half-plane,and the time-domain evolution of the field demonstrates a decaying behavior,with the late-time tail exhibiting a power-law pattern.These observations collectively suggest the stability of a Frolov BH against scalar perturbation.Additionally,our study reveals that the quantum gravity effect leads to slower decay modes.For the case of the angular quantum number l=0,the oscillation exhibits non-monotonic behavior with the quantum gravity parameter α0.However,once l≥1,the angular quantum number surpasses the influence of the quantum gravity effect.
