Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Three active noise control (ANC) systems, which incorporates different arrangements of the secondary loudspeaker, have been examined experimentally, based on the analysis of the characteristics of sound wave propagation in a duct. Measured transfer functions of the plant and the error paths show good agreement with the theoretically derived transfer functions in the acoustic modal frequencies of the systems. Real-time experiments shod a more effective noise attenuation with a tree-shaped configuration than with the traditional T-shaped ANC system. The symmetric arrangement of two secondary speakers in the tree-shaped system helps in compensating the node observed at 200 Hz in the error path. This compensation can also be achieved by using an equalizer. >
