摘要
综述了管道有源消声技术的声波干涉消声原理、阻抗控制消声机理以及传声器、扬声器和控制器元器件等的发展情况.重点论述了国外在管道有源消声技术研究中的研究成果和智能材料应用情况.预测了管道有源消声技术今后在消声机理研究与元器件研制方面的发展趋势.
The authors summarize the sound wave interference attenuation principle and impedance control attenuation mechanism of duct active noise attenuation technology, and the development of microphone, loudspeaker and controller elements. The research achievements and progresses, especially the applications of smart materials in this area, are particularly discussed. At last, the developing trends for further study on these subjects are forecast
