In particular, we analyze scalar, vector and gravitational perturbations of the black hole with the semianalytic WKB method. We analyze in detail the behaviour of the spectrum depending on the parameter p/q of the black hole, the quantum number of angular momentum and the s number. In addition, we compare our results with the classical solution valid for  $$p = q = 1$$  <math> <mrow> <mi>p</mi> <mo>=</mo> <mi>q</mi> <mo>=</mo> <mn>1</mn> </mrow> </math>  ."
