Abstract: In this paper, a performance prediction method is investigated for active noise control system. Based on active noise control principle, data measured both primary sound field and secondary transmitted channel are used to design and predict the control system. The prediction method is presented and applied in the control noise experiments of Chinese Y-7 aircraft. Satisfied results are obtained.
Keywords: active noise control, performance predicting, aircraft noise.
