| الوصف: | In this paper, we investigate the scalar perturbation over the Frolov black hole (BH), which is a regular BH induced by the quantum gravity effect. The quasinormal frequencies (QNFs) of scalar field always consistently reside in the lower half-plane, and its time-domain evolution demonstrates a decaying behavior, with the late-time tail exhibiting a power-law pattern. These observations collectively suggest the stability of the Frolov BH against scalar perturbation. Additionally, our study reveals that quantum gravity effects lead 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 $\alpha_0$. However, once $l\geq 1$, the angular quantum number surpasses the influence of the quantum gravity effect.
