In order to study the noise characteristic of wind turbine airfoils, the airfoil optimal design mathematic model was built based on airfoil functional integrated theory and noise calculated model. The new optimized objective function of maximizing lift/drag to noise was developed on the design angle of attack. Then, the comparison of sound pressure level between CQU-DTU-B18 and NACA-64-618 airfoil was analyzed under the same condition of wind tunnel experiment and wind speed. It is indicated that the changed trend of the predicted noise results are in agreement with that of the tested data, though there is a certain difference between the theory results and experiment data. Compared with NACA-64-618 airfoil, the CQU-DTU-B18 airfoil exhibits lower noise, which validates the feasibility of this design method. It is a guide to design wind turbine airfoil with lower noise and to reduce airfoil noise
