| Abstract: | Aiming at the peak noise induced by the time delay of the anti-noise source, the noise reduction effect and peak noise generation of periodic signals and random signals with different frequencies and different signal superimposed analog delay were analyzed. The peak noise induced by time-delay was processed. A kind of peak noise suppression strategy based on the fuzzy inhibit active noise control was proposed. Its effect for peak noise reduction was verified by the simulation result. |

| Keywords: | acoustics active noise control low frequency noise simulation delay peak noise fuzzy control |
