摘要：Noise pollution has become increasingly severe around the world due to fast urbanization.How to soundproof windows from outside noise is of significant interest for both academia and industry.This paper reports an experimental implementation of normalized minmax active noise control(ANC)algorithm on an open window system,where identifying the model of acoustic sound paths plays a central role.By doing this,traffic noise is attenuated by the ANC system,leading to a relatively quiet indoor environment,while the natural lighting and ventilation functions of a window are remained.Our experiments show that an average of 19dB(A)noise reduction is achieved.
