This paper systematically investigates the quasinormal modes (QNMs) of a scalar field around a charged loop quantum black hole (BH). The BH is characterized by two key parameters: the quantum parameter $b_0$ and the charge parameter $Q$. We explore two scenarios: one where the multipole quantum number $l=0$, in which only the gravitational potential is relevant, and another where $l > 0$, in which both $Q$ and $b_0$ jointly influence the quasinormal frequencies (QNFs). For $l=0$, quantum gravity effects lead to a pronounced overtone outburst in the QNFs, with the outburst and accompanying oscillatory patterns becoming more pronounced as the overtone number increases. For $l > 0$, the overtone outburst disappears due to the centrifugal potential's suppressive the quantum gravity effect. However, a non-monotonic behavior in the first two overtones with respect to $b_0$ is observed, indicating that subtle quantum gravity effects persist. This behavior vanishes as $Q$ increases, further confirming the suppressive influence of the centrifugal potential on the quantum gravity effect. |
