In the report, we present an accuracy improvement of the meshfree Finite point method. This high-order method has been used to solve the sound propagation problems, which can be modeled by linearized Euler equations. High accuracy has been obtained using polynomial reconstruction of variables involved in the Riemann solver. The order of the meshfree method will be verified on 2D acoustic pulse problem which serves as a benchmark problem with known analytical solution.
