In this paper, a new form of homotopy perturbation method (NHPM) has been adopted for solving second- rder linear hyperbolic telegraph equation. This new approach leads to the exact solution of one- or two-dimensional second-order hyperbolic equation. Computations of the examples reveal the simplicity and fewer manipulations in comparison with the usual method.
