  In this work, we numerically investigate the scattering and absorption cross
section of the massless scalar field from some well-known regular black holes
by using the partial wave approach. Our computational results indicate that the
larger the parameters, the lower the associated total absorption cross section
maxima. When compared to the Schwarzschild black hole, the scattering cross
section is enhanced in some regular black hole spacetimes, meanwhile the
scattering width is narrow in the forward orientation. Moreover, it is found
that the null geodesics of the critical impact parameter and the geometrical
optical value in the high frequency regime have similar changing behavior.
