| Abstract: | The wind duct was imitated to making an emulator of four typical fans equipments and decreasing the low-frequency quantity of hydrodynamic pulsation. Finally, the active NN control technique was provided, which is based on RBF, applies on the hydrodynamic pulse of the wind duct. Thus, the relative low-frequency attenuating quantity is so larger to exceed 50% sometimes, the absolute lowfrequency attenuating quantity is about 20dB of the mean and more 30dB of the maximum, according to A-weighted sound pressure level in the range of the low-frequency octave band. |
