This paper presents a frequency-domain method to compute noise radiated from the rotating source and scattered by the surface, where both the acoustic pressure and acoustic velocity of the noise radiated from the rotating thickness and loading sources are computed with the frequency-domain numerical method and the surface scattering effect is taken into account by employing the frequency-domain equivalent source method. To validate the above method, the analytical solutions for noise radiated from the rotating monopole and dipole point sources and scattered by a rigid sphere are proposed. A good agreement between the numerical results and the analytical solutions has been achieved. Moreover, the Isom noise consistency test is also carried out to validate the frequency-domain numerical method. The analysis of the computational error is investigated as well.
