  We study the quasi-normal modes for scalar, electromagnetic, and
gravitational axial perturbations in the Hayward regular black hole surrounded
by quintessence (HBH-$\omega_q$). Using the third--order WKB approximation we
can determine the dependence of the quasi--normal modes on the parameters of
the regular black hole and the parameters on the test fields. We also determine
the greybody factor, giving transmission and reflection coefficients of the
scattered wave through the effective potentials in the WKB approximation using
numerical analysis.
