Bardeen black hole surrounded by perfect fluid dark matter for a masslessscalar field. Our result shows that the oscillation frequency of quasinormalmodes is enhanced as magnetic charge $g$ or the dark matter parameter $\alpha$increases. For damping rate of quasinormal modes, the influence of them isdifferent. Specifically, the increase of dark matter parameter $\alpha$ makesthe damping rate increasing at first and then decreasing. While the dampingrate is continuously decreasing with the increase of the magnetic charge $g$.Moreover, we find that the increase of the dark matter parameter $\alpha$enhances the power emission spectrum whereas magnetic charge $g$ suppresses it.This means that the lifespan of black holes increases for smaller value of$\alpha$ and larger value of $g$ when other parameters are fixed. Finally, theabsorption cross section of the considered black hole is calculated with thehelp of the partial wave approach. Our result suggests that the absorptioncross section decreases with the dark matter $\alpha$ or the magnetic charge$g$ increasing.
